Telegram anti-spam bot
An anti-spam bot that shows its work.
Most Telegram anti-spam bots are keyword filters with a settings page. Targa is a screening engine: every message is scored by a classical, CPU-only detector, every action carries a structured reason you can pull with /why <id>, and the free tier stays free because the engine costs $0 per message to run.
What it catches
Homoglyph obfuscation
"c0inbаse" reads fine to a human and slips past blocklists. Targa normalizes lookalike characters before scoring.
Edit-after-post
Clean message in, spam edit later — a classic filter bypass. Targa re-screens on edit.
Admin impersonation
Lookalike names and avatars targeting your members in DMs and replies.
Floods
Burst attacks are contained as a pattern, not fought message-by-message.
Why explainability matters
Opaque moderation is the universal admin pain point: a member gets banned, nobody knows why, and trust erodes on both sides. Every Targa verdict is reproducible — verdict, score, and the exact signals that fired. Appeals stop being arguments.
When AI-driven spam needs more than the classical layer, the paid M2 tier adds LLM-grade detection for conversational scam funnels and hyper-personalized phishing.
