MT Security Assistant bot

A growing group sooner or later attracts spam, advertising bots and people who join only for links. Moderating by hand is unrealistic. MT·安全小助手 is a free group management bot: add it to your chat, open /settings and set the rules 🛡️

The interface is in Chinese, so below is a simple map of what to look for and how not to get lost.

What the bot is for

The bot belongs to the family of group helpers for administrators. By its description it is free and open: built on a well-known chat moderation solution, it provides a basic set of protections.

Typical jobs for a bot like this: spam defense, newcomer checks, greetings, scheduled messages and member management.

What you can configure

• Join check: a newcomer must confirm they are human before writing in the chat.
• Message filters: blocking words, links and repeated advertising messages.
• Auto-replies: answers to keywords such as a greeting or group rules.
• Buttons in messages: handy shortcuts to rules and FAQ.
• Schedule: messages that go out at the right time.
• Anti-flood: protection against floods of identical messages and raids.

Five steps to connect

1. Add the bot to your group.
2. Make it an administrator with the necessary rights.
3. Type /settings in the chat or in a private chat with the bot.
4. Pick your group in the menu.
5. Turn on protections one at a time and see how they behave.

If the language gets in the way

The menu is Chinese, but most items are clear from icons and switch positions. An enabled feature is usually marked with a symbol, a disabled one is not.

A handy trick: open the menu with your phone's translator, or take a screenshot and translate the text. You will find the right sections quickly. 🌐

Admin rights and caution

A moderator needs the right to delete messages and restrict members. Do not give more than needed, because a bot administrator holds serious power over the chat. 🔐

Start with the minimum: deleting messages and restricting members. Add the rest once you see it works as expected.

What to expect from protection

No bot catches all spam. Spammers change their wording, so once a week check the log and add new words to the filter. It takes five minutes.

Explain the rules to members in advance: a pinned message with bans and penalties cuts down on arguments. People follow what they see right away. 📌

In a large group, appoint a few human moderators. The bot removes routine work, but disputed cases are better decided by people.

Test first, then the whole group

Create a test group with two or three friends and try every rule there. That way you will not have to apologize to members if a filter blocks normal words by mistake.

If spam does not go away, add the newcomer check: it cuts off most automated joins. For public chats it is the most useful protection. ✅
