Every time for the last week at least that I've put in a report on what I believe to be a farming bot, as soon as I click on the report button, I am disconnected from the game.
I can only assume Blizzard doesnt like me reporting anyone....
Just had this issue as well, reported some dude dragging 5 or so alt accounts through content for paid power leveling (Assuming) and my toon cant connect to the server but all other toons log in fine, the report function is now broken =/
That's generally a ui or addon issue on your end. I can report without being dc'd.
