Anti-spam & moderation

The Telegram anti-spam bot that runs itself — no wall of commands.

Limzo keeps spam, scams and raids out of your group across the whole path a spammer takes — the join, the link drop, the flood, the fake-admin DM. It works from smart defaults you can adjust in a few taps, inside the same bot that already runs your stats and engagement. Free to start, on every plan.

Spam gone before anyone reads it

Scam messages, promo spam and copy-paste floods are removed automatically per your rules. A separate link safety scan checks every URL against a continuously updated database of known phishing and malware sites — the same protection your browser uses — and posts a public warning under a dangerous link so nobody taps it; Pro and Community can auto-delete instead.

The door and the room, both covered

Newcomer verification stops the scripted accounts that join open groups to spam. The cross-group network shield blocks links and senders already confirmed as spam by admins in other Limzo communities — so a brand-new threat is caught the moment it arrives in yours.

Humans decide the gray areas

For the calls only a person should make, /warn gives admins a shared strike counter that automatically mutes, kicks or bans at the limit you choose. The impersonator guard privately alerts you to members mimicking an admin. You set the policy; Limzo enforces it the same way every time.

What a Telegram anti-spam bot actually has to stop

Most group spam does not start with a message — it starts with a join. Scripted accounts enter open groups by the dozen to drop promo links, harvest members for private-message scams, or sit quietly inflating your member count until they wake up weeks later. From there it becomes link spam, repeated copy-paste floods, and the classic fake-admin DM scam where someone renames themselves to look like your team and messages your members in private.

A real anti-spam bot has to cover every step of that path, not just one. Limzo does: a check at the door, automatic removal of spammy messages and dangerous links inside the room, cool-downs for floods, a fair warning system for the human judgment calls, and a shield that shares confirmed spammers across the whole network so your group benefits from what every other group has already caught.

The full security stack, at a glance

Every layer below is included on the Free plan, and each has its own switch in the Mini App:

Newcomer verification — new members are muted until they tap a button proving they're human; unverified joiners are removed after a few minutes and can rejoin to retry.
Scam & promo removal — scam messages, promo spam and shady contact-me posts are removed automatically, per your rules.
Link safety scan — every shared URL is checked against a continuously updated database of known phishing and malware sites — the same protection your browser uses — and a public warning is posted under a dangerous link. Pro and Community can auto-delete instead.
Flood & duplicate control — copy-paste repeats and message floods get cool-downs instead of chaos.
/warn member warnings — a shared strike counter that automatically mutes, kicks or bans at the limit you choose.
Impersonator guard — spots members who join with, or rename to, a name mimicking one of your admins and privately alerts your team with one-tap Ban / Looks-fine buttons; Pro and Community can auto-act on clear impersonators.
Language lock (optional) — keeps the group in its own language through the same fair warning ladder.
Cross-group network shield — spam links and senders already confirmed in other Limzo groups are blocked automatically; your own allow lists and trusted users always win.
Member /report command — any member can flag a message by replying /report; admins get a private alert with one-tap Delete / Mute / Ban buttons.
In-chat admin commands — /ban, /mute, /kick, /unban and /unmute, with durations like 30m or 2h, silent to non-admins.
Ghost cleanup — deleted accounts still inflating your member list are counted in your weekly admin report and removed with one tap.

Nothing on this list needs a rule syntax or a trigger chain — every layer ships with sensible defaults and one switch. That is the difference between a security stack and a "basic captcha".

How Limzo's smart moderation works

One master switch in the Mini App under Moderate turns moderation on for the whole group — it is off by default, so nothing changes until you decide, and your exact settings are kept even while it is off. When Limzo joins, the links and @usernames already in your group description are treated as your own and pre-allowed, so moderation never fights your own content.

Underneath sit the layers, each with its own switch: newcomer verification, the link safety scan, flood & duplicate control, member warnings via /warn, an optional language lock, the fake-admin impersonator guard, and the cross-group network shield. Most enforcement rides one fair ladder — a warning first, escalation only at the limit you set — and admins and trusted users are always exempt. The full switch-by-switch reference lives in the moderation guide.

Automation-first vs command-driven — an honest take

Limzo covers the everyday moderation the large majority of groups actually need, and it does it without a manual: no custom rule syntax to memorize, no trigger chains to wire up. That is the point — protection that a busy admin can turn on and trust.

The honest limit: if what you need is a full custom trigger system, scheduled announcements, or granular command-driven admin workflows, a dedicated moderation toolbox such as Combot, Rose or ChatKeeper goes deeper on manual control. Limzo's distinctive value is doing solid, automatic protection and your analytics, levels and weekly highlights in one bot — one admin slot instead of a stack of single-purpose tools. Feature sets change over time, so check each product's current settings before you commit a critical workflow.

Common questions

Yes, for groups that want strong automatic protection without operating a command console. Limzo removes scam messages, phishing links, promo spam and floods, verifies new members, runs a /warn system with automatic enforcement, guards against fake-admin impersonators, and blocks spammers already confirmed across its network. It is not built to replace a heavy command-and-trigger toolbox, but it stops the spam the vast majority of groups actually face.

Automatically. Turn moderation on once in the Mini App under Moderate and Limzo runs from sensible defaults — no rule syntax, no trigger chains. You can tune each layer, choose the action at the warn limit, and add trusted users, but nothing requires a command manual.

Smart anti-spam moderation with newcomer verification, an impersonator guard, a link safety scan, member warnings, a language lock and the network shield are all available on the Free plan. Pro and Community add options like auto-delete for flagged links and automatic action on clear impersonators.

It is built to avoid that. Detection is deliberately cautious, admins and trusted users are always exempt, your group's own links and usernames are pre-allowed, and most enforcement is a warning on a fair ladder rather than an instant ban — so a rare false alarm is easy to undo and never costs you a member.

Yes. The impersonator guard watches for members who join with, or rename to, a name that mimics one of your admins or Limzo itself, and privately alerts your team with one-tap Ban / Looks-fine buttons. Pro and Community groups can set an automatic action on clear impersonations. Read the full fake-admin scam guide for how the scam works.
