SangMata: nickname change tracker

A "new" member shows up in your chat, but the message style looks suspiciously familiar. Yesterday they were under a different name, and today they changed the nickname and started over. SangMata is made for exactly that: the bot notices name and username changes and reports them straight into the group. 🔍

It is useful for admins, but it has a flip side for ordinary members. Let's look at both.

What the bot notices

By its description, SangMata tracks name and username changes and sends a notification to your group. You add the bot to a chat and it starts watching members.

Telegram keeps no public log of these changes, and the app has no built-in way to browse history. The bot knows only what it has seen itself in chats where it is present.

What admins use it for

• Fighting spam. A spammer changes the nickname, but the notification shows the earlier name.
• Trade and swap chats. You can see when a seller suddenly becomes a "different person".
• Transparency. Members know in advance that a nickname change will not go unnoticed.
• Moderation. Old complaints are easier to match with a new profile.

The developers say in the description: send the bot "Help" to see its list of commands. Project news is kept in the developer's channel, so read details there.

Connecting it to your group

1. Find the bot in search and add it to the group.
2. Grant admin rights if the bot asks for them.
3. Send "Help" and check the available commands.
4. Tell members that a bot like this is active in the chat.

The fourth step is not a formality. People have a right to know their nickname changes are recorded, especially in closed communities. 🤝

Where its power ends

The bot sees only what happened while it was around. If someone changed their name before it joined, or has been inactive for a long time, there is no history. SangMata does not turn you into an all-knowing detective.

It also shows no personal data such as a phone number or address. It deals with the open profile fields that everyone in the chat can see.

Privacy: what members should know

If you belong to groups with a bot like this, your name changes may be recorded. The developer mentions privacy settings that limit searches of your history. Check what the current version of the bot offers.

For your own safety, keep personal details out of your nickname: a real surname, a workplace, a phone number. If changes are recorded, an old nickname can stay visible. 🔒

Ethics and proportion

Tracking name changes fits moderation and protecting a chat. Using the data to stalk a specific person, pressure them or harass them is not acceptable. It crosses personal boundaries and may break the law.

A good rule: collect only what keeps the chat orderly, and do not publish someone's profile history without a reason.

Who it suits

Admins of large chats, moderators of trade and exchange communities, and anyone tired of spammers who keep changing nicknames. A small chat of friends usually does not need it.

Before adding it, decide how you will explain it to members. Openness answers half the questions and builds trust in moderation. ✅
