Mark Zuckerberg
Facebook founder Mark Zuckerberg may have set the record for being the youngest billionaire, but the company’s IPO might also put him in the books for paying the highest taxes. Since the 27- year- old entrepreneur plans to exercise stock options worth billions, his tax bill could reach as high as $2 billion. Reuters

There now two Mark Zuckerbergs in the world and one is being threatened with a lawsuit from Facebook.

An Israeli businessman formerly known as Rotem Guez changed his name on Dec. 7 to Mark Zuckerberg while he faced legal threats from Facebook for violating the website's terms and conditions. According to the lawsuit, the new Zuckerberg refused to disband Like Store, a company he created that claimed to sell Facebook Likes for brand pages.

Facebook sent a cease and desist order in September and asked the new Zuckerberg to not access Facebook's Web site. The new Zuckerberg then threatened to sue Facebook after the site shut down a previous account he created under the shared name in January, before he had officially changed his name.

If you want to sue me, you're going to have to sue Mark Zuckerberg, new Zuckerberg reportedly told Facebook.

The new Zuckerberg has created a personal Web site, MarkZuckerbergofficial.com, to gain support for his lawsuit. According to Time, he recently shared communications with Facebook's legal team which states that the company continues to gather evidence detailing additional illegal activities that the new Zuckerberg is participating in, adding that Facebook takes the protection and proper working of its network very seriously and is committed to keeping Facebook a safe place for users to interact and share information.

Facebook also requested that he confirm in writing that he will no longer access Facebook, nor develop any business offering related to Facebook in order to avoid whatever measures [Facebook] believes are necessary to enforce its rights, maintain the quality of its site, and protect its users' privacy and information.

In an e-mail to The Huffington Post, the new Zuckerberg said, Facebook decided to sue me after I myself, filed a law suit against them, in Israel.

I wanted that once they sue me, they'll face suing 'Mark Zuckerberg.' Facebook accused me of selling fictitious 'Likes', which is not true, our 'Likes' come from real users who want to receive our content, and instead of paying us with money, they pay us with 'Likes.' The idea was, if only 'Mark Zuckerberg' is allowed to sell likes, then for that matter, I'm 'Mark Zuckerberg.'

Facebook has yet to officially file a lawsuit against Zuckerberg.
