Telegram bot in Rust.
- If the user sends a message with a link but didn't interact with the group before, the message is deleted.
- URL blocklist; if message contains an URL from the blocklist, the message is deleted.
- 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).
- 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.
