Spam is di main pain of public Telegram chats. As soon as a group grows and shows up in search, promotional blasts, scams and bots start pouring in. One good anti-spam bot saves hours of manual moderation — but only if you understand how it works and how to set it up.
Types of spam
To defend yourself, it helps to sabi di enemy:
- Promotional blasts — links to third-party channels, products and services.
- Scam and phishing — "giveaways", fake support bots, harvesting codes and seed phrases.
- Flood and emoji spam — junk messages clogging di chat.
- Entry spam — bots joining in batches to later DM your 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 and — crucially — by meaning.
3. Behavior. Anti-flood (rate limiting) and analysis of new-account patterns.
4. Response. A clear ladder of sanctions: warning → mute → ban, wit logs and notifications.
Di weak link is usually di second layer: bots dat filter only by words let reworded spam through.
