this trash called wiggin#1713 at this trash clan keeps inviting me to his games and even after i blocked him he still keeps sending invites nonstop once every 3 seconds
This sounds a lot more like a game bug that’s causing the invites to be incorrectly auto-generated than someone manually sending them. Certainly not something that you should call someone out on publicly in the forums. Generally, if you put them on ignore and then re-start your Diablo client, it should stop.
