Getting started
Start ChatZilla, add it to your Telegram group as an admin and switch on the first rules: verification, filters and anti-spam, step by step.
1. Start the bot
Open @ChatzillaBot and press Start. The reply lists what the bot does and has the buttons you need next.
2. Add it to your group as admin
Press Manage chats, then Add chat in the mini app and pick the group in Telegram's own picker. The admin rights the bot needs are already selected, so confirming the picker adds and promotes the bot in one step. Other ways to add it are in Adding to a group, the rights themselves in Permissions.
3. Switch on the rules you need
Select the group in the mini app. Its settings are split into sections, each one switched on separately:
- Group join requests: screening of applicants for groups with join requests (Join requests).
- User Greetings: the welcome message and cleanup of "joined" and "left" service messages (Welcome messages).
- User Validation: the check new members pass (User verification).
- Media Filters and Message Filters, where the list of allowed bots is also kept (Media and message filters).
- Content Filter: stop words and required words (Word filters).
- Triggers, User Autoblock (anti-spam), Bot Message Settings, Karma and Group Localization (including the language filter).
A good first setup for an open group: a welcome message, verification with a button, links and forwards set to "Only for validated users", and anti-spam on.
4. Watch what it does
The Events Log shows every deletion, ban and verification as it happens, and Statistics shows the daily totals. See Statistics and logs.
Administrators of the group are never filtered or asked to verify. To see a filter in action, test it from a second account that is not an admin.
