Creating an Anti-Harassment Bot for Telegram: Templates Inspired by Psych Research

Hook: Stop watching toxic threads erode your community — automate calm, not punishment

Creators and publishers on Telegram tell the same story: a single heated exchange can derail a group, scare away subscribers and force admins into 24/7 triage. You need an anti-harassment bot that reduces escalation, protects people, and gives moderators time to make judgment calls — without writing a single line of irreversible code. This guide delivers code-agnostic templates for calm-response prompts and moderation signals grounded in psychological research and 2026 moderation trends.

Why this matters in 2026

Automated moderation is no longer optional. Volumes of UGC rose in late 2025 as creators consolidated communities on messaging platforms; at the same time, platforms accelerated AI-powered moderation tooling. But automation alone can inflame users if responses feel robotic or accusatory. Developers and channel owners now balance three imperatives:

• De-escalation: Calm interventions that reduce defensiveness.
• Accuracy: Signals that minimize false positives and respect speech boundaries.
• Privacy & safety: Minimal logging and transparent policies to avoid legal traps post-2025 security scandals.

Principles from psychology: What calm responses look like

Psychologists studying conflict emphasize two core moves that reduce defensiveness: reflective validation and non-blaming invitations. A 2026 review of de-escalation techniques highlights brevity, acknowledgment of feelings, and a path forward as crucial components.

“When language signals understanding and offers an easy exit, people are less likely to double down.”

Translate that into bot behavior: short, human-sounding messages that validate feelings, avoid assigning malicious intent, and provide options (clarify, move to private, use report). Below are the calm-response templates you can adapt.

Calm-response templates (code-agnostic)

These templates are deliberately short and neutral so they can be ported into any bot platform or moderation workflow.

1) First nudge — gentle validation

Use when a message is heated but not abusive.

• Template: “I hear this is important to you — let’s keep the chat constructive. Could you clarify the main point?”
• Why it works: Validates emotion, invites clarity, reduces the urge to retaliate.

2) Soft reflection — reduce defensiveness

Use when two participants are arguing and tone is escalating.

• Template: “It sounds like there’s frustration here. If you want, I can move this to a private thread or notify an admin.”
• Why it works: Reflects emotion and offers an easy exit with an immediate next step.

3) De-escalation + options — bridge to private resolution

Use before issuing any moderation penalty.

• Template: “We value respectful discussion. You can explain your point again more calmly, message the user privately, or request admin help with /report.”
• Why it works: Gives agency and actionable choices; avoids unilateral enforcement without human review.

4) Immediate safety flag — when threats or doxxing appear

Reserved for high-severity content. Keep concise and clear.

• Template: “This message appears to violate group safety rules. Admins have been notified and the message will be reviewed. If you are in danger, contact local authorities.”
• Why it works: Signals seriousness, triggers escalation, and reminds users about safety protocols.

5) Private moderator prompt — preserve dignity

Sent to the offending user as a private message.

• Template: “We noticed your recent message in [Group]. It came across as hostile. If you’d like to continue the conversation respectfully, reply here or wait 10 minutes before posting again.”
• Why it works: Prevents public shaming and reduces heated back-and-forth.

Moderation signals — what to watch and why

An effective bot blends surface signals with context. Use multiple signals to reduce mistakes: one cue alone should rarely trigger removal. Below is a prioritized list and how to score them.

Primary signals (high-weight)

• Reported by human: Direct user report (highest priority).
• Explicit threats / doxxing keywords: Exact-match patterns for personal data, threats, or slurs.
• Repeated targeting: Same user mentioned with negative language across multiple messages.

Secondary signals (moderate-weight)

• Sentiment drop: Sudden negative sentiment after neutral/positive messages.
• All-caps / excessive punctuation: Indicator of shouting.
• Message velocity: High frequency from a single user suggesting trolling.

Contextual signals (low-weight but useful)

• Conversation thread length: Longer threads with back-and-forth increase risk.
• User history: Prior warnings or strikes should raise score.
• Time of day / events: Heated events (e.g., live launches) increase likelihood of false positives.

Action matrix: map signals to actions

Combine scores from signals above into a simple tiered response. Keep thresholds adjustable and log decisions for review.

1. Tier 0 — Nudge (score 1–3):
   • Send first nudge calm-response template in-channel.
   • No logging beyond timestamp and user id.
2. Tier 1 — Private warning + cooldown (score 4–6):
   • Send private moderator prompt; impose short posting cooldown (e.g., 10 mins).
   • Log message excerpt and moderator notification.
3. Tier 2 — Temporary restriction (score 7–9):
   • Mute or restrict posting for 24–72 hours; pin explanatory notice to group.
   • Automatically notify admins with audit evidence.
4. Tier 3 — Immediate removal & admin escalation (score 10+):
   • Remove message, optionally remove user, notify admins and offer appeal link.
   • Log full message, context, and analyst notes for review.

Human-in-the-loop: when automation must pause

Automated calm responses should reduce workload, not replace human judgment. Escalate to human moderators when:

• Signal score crosses Tier 2.
• Multiple users or public figures are involved.
• Potential legal risk exists (threats, doxxing, child safety).

Design the bot to present concise, actionable evidence: message IDs, timestamps, a one-line sentiment summary, and suggested actions. This reduces admin cognitive load and speeds resolution.

Audit logs & transparency templates

Transparency builds trust. Publish a concise policy for your group and append an audit record to each moderation action.

Audit log entry (template)

Include in moderator dashboard or logs:

• Action ID: auto-generated
• Timestamp: UTC
• User: handle + id
• Trigger signals: [reported, sentiment:-0.78, allcaps:yes]
• Bot action: private_warning + 10m cooldown
• Moderator notes: optional free text

Privacy, security and legal guardrails (2026-aware)

After the 2025 wave of account-targeting and password-reset attacks across platforms, creators are more sensitive to how automation collects and stores data. Keep these guardrails:

• Data minimization: Store only message excerpts required for review; auto-redact PII unless needed for legal reasons. See Protecting Client Privacy When Using AI Tools for practical redaction checklists.
• Retention policy: Default to 30–90 days for logs unless a case is escalated.
• Admin access controls: Two-person review for removals affecting revenue or reputation.
• Opt-in transparency: Notify group members that automated moderation is active and provide an appeal route.
• Security posture: Use encrypted storage and rotate keys; limit webhooks to verified endpoints.

Reference: security reporting from late 2025 underscored how mishandled automation hooks can become attack vectors. Treat bot infrastructure as sensitive as any platform integration.

Test plan and metrics — measure de-escalation, not just removals

Good moderation improves community health. Track the right metrics and run A/B tests to tune thresholds and message wording.

Key metrics

• Time-to-resolution (TTR): From first heated message to closed incident.
• Recurrence rate: % of users returning to hostile behavior within 30 days.
• False positive rate: % of automated actions reversed by moderators.
• User retention: Member churn in the 7–30 days after automated moderation events.
• Satisfaction: Post-incident anonymous survey for involved users.

A/B test ideas

• Compare “validation-first” vs “policy-first” nudges for Tier 0 events and measure escalation reduction. Use frameworks from the Edge Signals & Personalization playbook to instrument tests.
• Test private vs public warnings for repeated offenses and track recidivism.
• Alter cooldown length (10 vs 30 minutes) and observe effect on message velocity.

Operational playbooks: scenario-driven templates

Below are real-world inspired scenarios with exact flows you can implement in any bot framework.

Scenario A: Heated disagreement between two members (no slurs)

1. Signal: Sentiment drop + reply chain length >3 -> score 3.
2. Bot action: Send first nudge in-channel using Template 1.
3. If further escalation within 10 minutes -> send Soft reflection (Template 2) and private warning.
4. If no improvement within 30 minutes -> mute offending user for 24 hours and notify admins.

Scenario B: One user targets another with repeated insults

1. Signal: Repeated targeting + reports -> score 7.
2. Bot action: Immediate private warning + 24-hour posting restriction. Notify admins with audit log.
3. Admin review: Confirm and escalate to temporary removal if pattern persists.

Scenario C: Doxxing or explicit threat

1. Signal: Explicit doxxing keywords or threat pattern match -> immediate Tier 3.
2. Bot action: Remove message, notify admins, message victim with safety resources and appeal route.
3. Document and preserve logs per legal requirements; consider law enforcement if credible.

Case study (hypothetical) — creator community de-escalation

In late 2025, a mid-sized creator group (35k members) added a calm-response bot as part of a push to scale. After three months implementing the templates above, they observed:

• 35% drop in public argument length (avg messages per heated thread fell from 12 to 8).
• False positive reversal rate under 4% after human-in-the-loop tuning.
• Member retention improved: churn among active contributors dropped by 6%.

Key lesson: the bot reduced friction for moderators and preserved the community tone without heavy-handed censorship.

Common pitfalls and how to avoid them

• Over-automation: Don’t auto-remove on weak signals — prefer nudges first.
• Robotic language: Test phrasing with members; human-sounding but concise messages perform better.
• Bias in keyword lists: Regularly audit word lists for cultural context and false positives.
• Privacy slip-ups: Avoid storing full conversation history without consent.

Implementation checklist (code-agnostic)

1. Define your group safety policy and publish it to members.
2. Select signals and assign weights; set initial Tier thresholds.
3. Import calm-response templates and map them to Tier actions.
4. Configure human escalation path and audit logging retention.
5. Run a 30-day pilot, track key metrics, and iterate on phrasing and thresholds.

Final considerations: evolving trends into 2026

Expect three shifts to influence anti-harassment bots in 2026:

• On-device moderation: More privacy-respecting, lower-latency signals run locally.
• Hybrid AI + human models: Automation triages while humans handle edge cases.
• Regulatory pressure: Increased requirements for appeal processes and transparency, driven by policy changes seen in late 2025.

Design your bot and templates to be adaptable. Language that feels calm and human in 2026 may need retuning as community norms shift.

Actionable takeaways

• Use short, validating messages as the first line of defense to lower defensiveness.
• Combine multiple moderation signals to reduce false positives and bias.
• Keep humans in the loop for Tier 2+ events and legal-risk situations.
• Publish clear moderation policies and maintain minimal, time-limited logs to respect privacy.
• Measure impact with TTR, recurrence, false positives and member satisfaction — not just removals.
