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

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 spam links and @usernames across the whole network so your group benefits from what every other group has already caught.

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 Ultra 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 try to mimic one of your admins and privately alerts your team with one-tap Ban / Looks-fine buttons; Pro and Ultra 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, @usernames and channels 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.
• Sticker pack blocking — reply /blockpack to any sticker and Limzo deletes stickers from that whole pack from then on; nobody is muted for a sticker.
• Ghost cleanup — deleted accounts still inflating your member list are counted in your weekly admin report and removed with one tap; Pro and Ultra can have them removed automatically.

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".

One master switch in the Mini App, Moderation, 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.

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.

Limzo covers the moderation 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.

With a command-driven bot such as Rose, Combot or ChatKeeper, protection is only as good as the rules your admins write and keep up to date. Limzo ships those rules built in, and adds your analytics, levels and weekly highlights in the same bot — one admin slot instead of a stack of single-purpose tools. Already running one of them? Add Limzo next to it, let it run for a week, then switch off the duplicate captcha and filters.
