Dana White loves a good fight.
But the Ultimate Fighting Championship president may have second thoughts about mixing it up with members of the hacker collective Anonymous on Thursday night on Twitter, where he was on the receiving end of a brutal punch.
White's personal information, including his Social Security number, cellphone number and address, was published online just moments after the exchange, in which he defended his company's support of the controversial -- and now-shelved -- Stop Online Piracy Act.
The UFC's website was also hacked for the second time in a week.
The mixed-martial-arts promoter's parent company was a supporter of SOPA, which was intended to crack down on digital piracy. The company, Zuffa, says many of its fights are posted illegally online, either for free or with the pirate sites selling advertising on them.
The back-and-forth kicked off shortly after 9 p.m. when one of the more popular Twitter accounts associated with Anonymous called out White -- an avid Twitter user -- for comments he made in a recent interview.
