Choosing a moderation bot seems simple: add it to the chat — done. But a month later it turns out the bot doesn't catch scams in DMs, is configured only by commands, and half the features you need cost extra. To avoid redoing everything, it's worth choosing deliberately.
Below are seven criteria we recommend for evaluating any bot, with an explanation of why each matters and what to look for.
1. Semantic anti-spam, not just keywords
The most common mistake is picking a bot that filters by a list of banned words. Spammers bypass that in a minute: swap letters for look-alikes, add spaces, send an image instead of text. A good bot analyzes the meaning of a message and the sender's behavior, not just specific words. Ask yourself: what happens if the spammer rewords the message? If the bot lets it through, the protection is weak.
2. Entry verification
Most spam comes from bots that join automatically. A CAPTCHA or entry check stops them before they start posting. It should be non-annoying for real people: math, button choice or emoji — quick and clear.
3. A web panel instead of chat commands
Command-based setup is painful: you have to remember the syntax, keep a cheat sheet, and it's easy to make mistakes. A web dashboard where features toggle on and off saves hours and reduces errors — especially with multiple admins.
4. Channel support, not just groups
If you have a channel (or a channel + chat combo), make sure the bot supports scheduled posting, auto-delete and channels. Many bots are group-only and useless in a channel.
5. Languages
If your audience is international, the bot's interface and messages should be in their language. Bots with 2 languages limit you; 50+ language solutions don't.
6. Transparent pricing and a free start
A good bot lets you try for free and honestly shows what's in each plan. Be wary if key features (anti-spam, logs) are locked behind an expensive subscription with no trial.
7. Live support and a knowledge base
Sooner or later a setup question comes up. Having support and a clear knowledge base saves time and nerves.
Common mistakes
- Choosing by popularity. A well-known bot isn't necessarily right for you.
- Looking only at price. A free bot that lets scams through costs more — in reputation.
- Ignoring channels. You'll end up buying a second bot.
- Not testing in practice. The best test is to add the bot to a test chat and try to "break" it with spam.
How to test a bot in 15 minutes
1. Add the bot to a test chat and grant admin rights.
2. Enable basic protection and join with a second account.
3. Try sending a link, spam and a reworded "banned" message.
4. Check entry verification and how convenient the panel is.
5. Count how many actions you had to do by hand.
