JWoww has certainly done a lot of controversial things over the years.
Changing her Twitter icon to a swastika is not one of them, however.
In addition to pulling that stunt, a hacker changed her bio to "Jersey Shore sluts getting ran daily. You can mark Sammi and JWoww off the list."
JWoww was, understandably, quite upset about the hacking. She tweeted at two users she believed to have been involved, writing, "Pathetic losers..."
"U wanna come at me meet me face to face! Bitch asses think ur cool hacking. Lets go! Loser ass thinks its cool to hack...Think ur cool? Ur a loser. Bitch!"
