The Twitter account widely believed to belong to right-wing Norwegian terrorist Anders Behring Breivik was hacked on Sunday by a person or group claiming affiliation with Anonymous Norway.
The account—which hasn't been confirmed as belonging to Breivik, though seems likely to be his—seems to have been seized at around 3:30 p.m. ET, at which point the hackers Tweeted out two really hilarious jokes about prison rape (you can see above; the Tweets were later deleted). The hackers called Breivik a "sick disgusting fuck" and announced that the account had been "seized by NORIA."
And then, having gotten the rape jokes out of their systems, the hackers turned to the obligatory incoherent statement of intent: "We want Anders to be forgotten. Labels like "monster", or "maniac" won't do either. Media should call him pathetic; a nothing. #Forgethim." (Okay, guys! Whatever!) "This twitter account will be deleted soon. Forget Anders," they finished.
As of the writing of this post, the Twitter account still exists.
