Antiubot: userbot ban for groups

An account with a pretty avatar joins your chat, writes "hi, how are you" and a minute later floods the group with links.

That is not a living person but a userbot: a script running behind a regular profile. Ordinary filters often miss it because it looks human from the outside. Antiubot was made to catch exactly these.

The profile has two lines in English and Spanish: it bans userbots and annoying spam bots. Short and to the point. 🚫

Userbot versus regular bot

A regular Telegram bot is easy to see: its username ends in "bot" and it works through the official bot interface. A userbot is built differently. It drives a real person's account, and from the outside it is just another user.

That is why protection from userbots differs from protection against ordinary advertising bots. Behavior checks help here: message speed, identical texts, links right after joining, mass invitations.

What the bot offers

• /start launches the bot.
• /lang changes the interface language.
• /config opens the settings for your group.
• /donate lets you support the project with any amount you choose.

The profile mentions English and Spanish, and /lang lets you pick the bot's language. 🌐

Set up in five minutes

1. Add the bot to your group or supergroup.
2. Make it an admin with the right to ban members and delete messages.
3. Open /config and look at the available options.
4. Choose your language with /lang.

Admin rights are needed because Telegram will not let a bot remove someone else's account without them. No other powers are required. 🔐

What userbot spam looks like

Not every admin knows the signs, but they are easy to learn.

• Instant ads. A new member posts a link within seconds.
• Private message pitch. It invites you to "discuss a great offer" in a direct chat.
• Suspicious profile. A fresh account, an attractive photo, an empty bio.
• A wave. Several similar profiles arrive a minute apart.

If you notice this, do not reply and do not open the link. In private messages, userbots most often lead to phishing or paid "channels". ⚠️

One bot does not replace rules

Banning works as a filter. To keep a group alive, combine the bot with simple habits: pinned rules, a welcome message for newcomers and a link limit for the first hours in the chat.

If the bot errs and removes a real person, you can bring them back manually by lifting the ban in the member list. Set a rule to review doubtful cases rather than trust automation blindly.

Developer and support

The project has a separate help group, and /donate lets you support its author. If something goes wrong, check the admin rights first and reopen the setup through /config.
