Spam is the main pain of public Telegram chats. As soon as a group grows an shows up in search, promotional blasts, scams an bots start pouring in. One gud anti-spam bot saves hours of manual moderation — but only if iu understand how it works an how to set it up.
Types of spam
To defend yourself, it helps to know the enemy:
- Promotional blasts — links to third-party channels, products an services.
- Scam an phishing — "giveaways", fake support bots, harvesting codes an seed phrases.
- Flood an emoji spam — junk messages clogging the chat.
- Entry spam — bots joining in batches to later DM blong iu members.
Each type needs its own layer of protection — so a single filter isn't enough.
Layered protection
Reliable protection isn't one filter but a chain of layers, each stopping its own threat:
1. Entry. Verification/CAPTCHA stops bots before they start posting.
2. Messages. Filters by words, links an — crucially — by meaning.
3. Behavior. Anti-flood (rate limiting) an analysis of new-account patterns.
4. Response. A clear ladder of sanctions: warning → mute → ban, witim logs an notifications.
The weak link is usually the second layer: bots that filter only by words let reworded spam through.
