How to disable such garbage when a user writes a message to a group, the group automatically sends "Hello, Petya" in response

Answer 1

1) disable callback. Or chop off the event a new message.
If it doesn’t help, then all the tokens of the group are far away.
If it didn’t help, they drank all of the editors / admins, change the pass from the account
