Facebook has threatened to sue Mark Zuckerberg, an Israeli entrepreneur who recently took the social network founder's name. The new Zuckerberg, born Rotem Guez, legally changed his name Dec. 7.

Zuckerberg II's website, MarkZuckerbergOfficial.com, states that he first filed a lawsuit against Facebook in January, after the social network refused to give him access to his profile, which it had shut down.

Zuckerberg (all further mentions refer to the Israeli entrepreneur) co-founded Like Store, a social marketing company, which sells companies Likes for their brand pages. The site states (translated), "Are you sad no one's visiting your Facebook Page? We have a solution! Need 1,000 Likes? We'll get them for you. Need 5,000 Likes? We'll get them for you. Need 10,000 Likes? We'll get them for you."

In September, Facebook's law firm Perkins Coie threatened to sue against Zuckerberg, claiming the Like Store violated the social network's Terms of Service, by selling brands fans. The threat instructed Zuckerberg to shut his company and never return to the social network for any reason.

Zuckerberg officially changed his name Dec. 7. In the below video of his trip to the Interior Ministry to make the switch official, he says he plans to change his family's names as well. One week later, Facebook again threatened a lawsuit against Zuckerberg's still existing Like Store. Little did they know, they were threatening someone with the name of their own founder.

Though legally Facebook can, of course, sue someone named Mark Zuckerberg, it makes for quite the funny tale.

Perhaps anticipating the media attention he would receive, Zuckerberg has set up an Internet campaign for his new persona, including a Facebook Page and Twitter account, @iMarkZuckerberg, suggesting that he's ready to make a splash with his new identity. His Facebook Page includes photos of his new identification card and passport.

Do you think the new Zuckerberg was ridiculous to change his name or has he pulled off a brilliant marketing stunt for his startup? Let us know what you think.
