I was replying to your other thread, but I’ll just paste it here instead and close that one.
If she removed the person from their BattleTag/RealID friend list, it automatically removes her from theirs. They’d only be able to have individual characters friended to see if that character is online or not.
Is she reporting as “ongoing harassment”? We don’t “ban” an account immediately, but if they are continuing the communication the penalty may including temporary suspensions, which do escalate if they continue the behavior.
Just to be sure, can you give me a ticket ID from one of her tickets? That has no identifiers in it, so is safe to post.
