Just now I encountered griefing by constant spam of friend invite/removal of invite spam so either I had dozens and dozens of friend invite windows piled on top of each other or the window just would not go away. Clicking the ignore button did nothing to stop the spam. I had to right click and carefully and by luck click ignore player on their name in chat.
My privacy settings have me set to be invisible to non-friends but at the time I was broadcasting on Twitch. I only had one visible viewer chatting though.
Before this friend invite spam occurred I also received a bridge invite window which YOU CAN NOT GET RID OF! Clicking decline DID NOTHING!
I am posting this here and copy/pasting to bug reports as well once I am back in-game and have reported this in bug reports there, received a ticket number, and posting in bug reports forum here with the ticket number.
