How to disable PMing a bot?
Or how to forbid the bot to respond in a personal?

Answer 1

There is such a function - stop and block.
The bot itself cannot start the dialogue first.

Answer 2

Mneee ...
1) If you didn’t subscribe, then this is SPAM and you need to complain. To ban the bot to the huntsmen.
2) If subscribed, then there must be an unsubscribe interface.
3) If there is no unsubscribe interface, write to the owner of the bot to disconnect you and / or fasten the unsubscribe. Better, of course, “and”, because the lack of the possibility of unsubscribing is bad manners and smacks of SPAM.
