I don't see anything earth shattering here. Am I missing something? I thought that always happened in Guild Wars 2. And the title makes it sound like 325k people assembled online to witness the event.
Wholly uninteresting. And it's not really unique to GW2, of course. Banning after players are caught cheating happens every day in online games.
I guess the difference is normally players are simply banned and maybe a forum post lets everyone know if the player was famous, instead of an admin logging in, removing gear, suiciding and then deleting the character and then banning the account which is 100% for dramatic effect. I guess this was congenial for the 'journalist' who likes to use dramatic effect in his titles himself.
