How we chose
We set up a test group and simulated common attacks: a burst of 10 identical messages in 5 seconds (flood), a fresh account posting a link with crypto-scam wording, and a message repeated by 3 accounts within a minute. We measured how fast each bot reacted, whether it muted or banned by default, how easy it was to add custom word/link blacklists, and whether false positives hit a real conversation during the test.
Moderation & anti-spam
How to choose an anti-spam bot
Reaction speed matters more here than for almost any other bot category — spam and flood attacks do damage in seconds, not minutes. Look for automatic flood detection (e.g., muting anyone who sends more than N messages in a short window), a customizable word and link blacklist, and CAPTCHA or challenge-on-join for new members, since most spam in Telegram groups comes from accounts created and used within minutes.
What to check before trusting a bot
Anti-spam bots need admin rights (ban/delete/pin) to work, so check who runs the bot, how long it's been active, and whether it logs or stores the messages it processes — a bot with broad admin rights in a large paid community is a real trust decision, not a convenience feature. Test the false-positive rate: an over-aggressive bot that bans regular members for posting a normal link is worse than no moderation at all. Also confirm whether moderation actions are logged to a separate admin channel, so you can review and undo mistakes.
Free vs paid
Free tiers usually cover flood control, basic blacklists, and join captchas for one or a few groups. Paid tiers typically add AI-based spam classification (catching disguised scam text, not just keyword matches), multi-group management from one dashboard, and detailed analytics on what got blocked and why. For a small community, free anti-flood and a keyword blacklist cover most real threats; large or monetized groups benefit from smarter, paid filtering.
Frequently asked questions
Is there a free anti-spam bot for Telegram groups?
Yes, most anti-spam bots offer a free tier with flood control, a basic word/link blacklist, and join verification, which covers the majority of spam in small to mid-size groups.
Does the bot moderate automatically, or do I need to set rules myself?
It does both: flood and duplicate-message detection usually work out of the box, but word blacklists, ban thresholds, and captcha difficulty need a few minutes of setup to fit your group.
Can it filter messages by specific words or links only?
Yes, all the bots we tested support a custom blacklist of words, phrases, and domains, and most let you set whether a match triggers a warning, a mute, or an instant ban.
