RefenseBot

RefenseBot RefenseBot is an AI-powered Discord moderation bot built around the philosophy of Refense, the balance between offense and defense. This Bot has functionality limited per server, so moderation between servers does not carry over. By analyzing behavior across messages, Refender measures 4 parameters: Hate, Sexual, Concern, and Scam to assess user risk over time. It tracks dangerous behavior, highlights patterns, and helps communities maintain balance.

Core Idea Every message is analyzed and scored across four major categories:

Hate Covers toxicity, harassment, threats, and violent intent.

Sexual Covers sexual content, including severe escalations.

Concern Covers self-harm and distress indicators.

Scam Covers scam indicators, typically from Mr. Beast scams

These scores are combined into a Danger Score, which contributes to a persistent user risk profile.

Instead of averaging all messages, Refender stores the Top 10 most dangerous messages from each user and calculates their overall danger based on those peak behaviors.

This preserves important signals and prevents dangerous behavior from being diluted by normal conversation.

Disclaimer AI moderation is imperfect.

Refender is designed to assist moderators, not replace them. Context, intent, and human judgment remain critical.
