Telegram user information

Myran said:

Name and username history can be found using the SangMata bot. There are also a few bots that can help you find out which groups you've joined, though the last time I checked, they had all gone paid. They might still allow a few free lookups. Using third-party clients like Nekogram or Swiftgram, you can approximately determine the geographical location and the date of joining of a user.
