Telegram bot in Rust.

  1. If the user sends a message with a link but didn't interact with the group before, the message is deleted.
  2. URL blocklist; if message contains an URL from the blocklist, the message is deleted.
  3. Welcome message (so, not so tacit, huh?). The main idea is to tell people how to share content in the group (use Gist, not paste images or code directly, etc).
  4. Validate that the account is a real person? ("Click here to confirm you're a person") This doesn't invalidate point 1, as the person may connect, click the link and then simply some automate process post content.
