AntiUserbotsBot: Button vs Userbots

You open a group, and a week later it fills with strange accounts: ads, links to easy money, invitations to dubious channels. Every admin knows the picture. AntiUserbotsBot targets exactly this problem, and does it very simply. 🛡

The bot shows a newcomer a button. Until it is pressed, the person cannot write in the group. If it is not pressed in time, the person is removed.

What a userbot is and why it hurts

A userbot is an ordinary user account run by a program. It looks like a real person, can join groups and can send messages in bulk. That is why standard bot protection often misses it.

Spammers use such accounts to enter chats quickly and in large numbers, post ads and vanish.

How it works: one button

The idea is plain. When a new member joins, the bot sends a message with a button. A real person presses it in a second, while a script not built for that action cannot.

1. A newcomer joins the group.
2. The bot asks them to press the button.
3. If they press it in time, they get the right to write.
4. If not, the bot removes them after the set time.

Setup in a minute

Add the bot to your group and give it administrator rights so it can restrict and remove members. That is a standard requirement for helpers like this.

Then use /config and set how long people get to press the button. Too short and it may remove real people. Too long and it leaves a window for spammers. Start with a moderate value and adjust from experience.

Two commands, no complicated menus

• /config sets the time allowed to press the button.
• /donate shows a link if you want to support the author.

The bot description is written in two languages, Spanish and English, and the bot is made by an independent developer.

What the bot will not replace

The button filters out automated accounts, but it cannot stop a live person determined to make noise. For that you need chat rules, clear penalties and a few moderators.

Pin short rules in the group, let only trusted members post links and turn on slow mode if needed. The bot guards the door, and you keep order inside. 🧹

Before you launch

Tell members that joining requires pressing a button, otherwise newcomers will get confused. Test with a spare account to confirm the bot sees the join and has the right to remove people.

If a needed permission is missing, recheck the admin settings in your group.

Think ahead about what to do with real people the bot removes by accident. They may simply miss the button or join and close the chat at once. Leave a way to reach an admin in the group description so such a person can return through a fresh invite.

Once a week, review the member list and recent complaints. If spammers still slip through, shorten the time to press or tighten the rules for newcomers. Protecting a group is a habit, not a one-time setup. 🔍

Finally, guard your invite link. If it sits in the open, spammers will find it faster than you can react. For closed groups it is handier to issue links limited by time or number of joins.
