Spam gone before anyone reads it.

Our moderation bots remove spam, raids and link floods inside the group in milliseconds, with per-chat rules and a record of every removal. Our own link remover runs in 81,300 groups.

Our link remover protects 81,300 Telegram groups. On 11 September 2026 we moved it from Python to Go in one dyno restart, with 10–15 seconds offline and every group’s settings intact.

What a KustBots moderation bot does

Removes links, invite spam and forwarded ads, including in edited messages.
Blocks spam phrases, with admin commands to add, remove and list them.
Stops raids and floods with per-chat limits.
Keeps each group’s rules separate, updated live without a redeploy.
Logs every action, so a disputed removal can always be explained.

Built to survive a restart

When a large bot restarts, Telegram may hold tens of thousands of old updates for it. A naive bot spends minutes clearing them and answers nothing new. Ours drop the backlog on startup and ignore anything older than a minute, so the queue stays near zero.

Moderation & Filtering

Spam, massive raids, and malicious link floods handled directly inside the group before any members read them. We use per-chat policies and heuristic rules that can be updated on the fly without a redeploy. Every removal is strictly recorded in an immutable audit log.

Bot Cloning

One robust codebase deployed dynamically per customer with securely isolated config, encrypted tokens, and separate storage. A new feature ships to thousands of instances simultaneously, but a configuration mistake reaches none of the others.

Questions

Asked and answered.

Can the bot remove links but allow admins to post them?

Yes. Rules are per chat, and admin links can be allowed or removed as each group prefers.

Will it slow down in very large groups?

No. The link remover is written in Go and runs across 81,300 groups; per-message decisions take milliseconds.

Can you build a moderation bot with our own rules?

Yes. We build custom moderation logic, from keyword lists to AI-assisted classification.
