Database leak at LivegramBot
Recently a popular feedback bot reported a database leak. The bot is commonly used for anonymous feedback to Telegram channel administrators. To protect the bots, all linked bot tokens will be revoked by the Telegram team.
To keep your bot working as before, you need to manually update the tokens for all Livegram bots in @BotFather and in @LivegramBot settings. If you won't do this, your bot will stop working soon.
What should the bot owners do:
1. Open @BotFather, send /mybots command.
2. Choose your bot from the list.
3. Tap API Token, then Revoke current token. After that, send the new token to @LivegramBot.
