Anti Spam Bot for Telegram Chats

You open your group and find three casino ads, invitations to "investment" channels and faceless accounts posting the same line. Deleting them by hand can eat an evening. Anti Spam Bot takes that chore over 🧹

The bot has about 64 thousand users, and tens of thousands open it in a month. The interface comes in Russian and English.

Set it up in five minutes

1. Open the bot and press the start button.
2. Add it to your group.
3. Make it an admin with the right to delete messages.
4. Optionally allow it to restrict members, so offenders do not come back.
5. Post something in the chat and check that the bot reacts.

Without admin rights no anti-spam bot can work: Telegram will not let it delete other people's messages.

What spam looks like in practice

Most often groups get mass mailings with outside links, easy-money offers, channel ads and bots that join in batches. Sometimes a spammer just pastes one message ten times in a row.

A decent filter looks at a combination of signs: a fresh account, a link in the very first message, repeats. A single sign proves little, so the chat owner needs a way to quickly restore anything deleted by mistake.

Where to get help

The project runs a separate support bot and a separate news channel. If something breaks or settings confuse you, ask there instead of commenting under random posts. Links to both sit in the bot's profile.

The news channel helps when features change: you learn about updates before you run into them in your chat.

Spam through a newcomer's eyes

A new member joins and within the first minute gets a private message from an "admin" asking them to follow a link. It is a classic scheme, and it thrives exactly where moderation has gone slack.

Remind people in a pinned message: real admins never message first and never ask for passwords. One such paragraph protects people better than any filter 🔒

A bot cleans spam out of the shared chat but cannot control private messages. There it comes down to the attention of the members themselves.

What Telegram already does

In groups above 200 members Telegram has its own spam protection with an aggressive mode. It uses the platform's own models and deletes suspected spam. Admins can turn it on in the group settings.

The built-in filter and a separate bot work well together. The first catches the obvious, the second adds rules tuned to your community.

Admin habits that save a chat

• Limit the permissions. Give the bot only the rights you actually need.
• Read the admin log. Once a week, check who was removed and why.
• Write rules. A pinned message with the list of bans ends most arguments.
• Keep moderation on. Spammers find open chats within hours.
