There is a new Mark Zuckerberg in town and he doesn't run Facebook.
An Israeli entrepreneur formerly known as Rotem Guez is showing off his marketing skills by changing his name to the same as the founder of Facebook.
"If you want to sue me, you're going to have to sue Mark Zuckerberg," he said.
The new Zuckerberg also is steeped in the technology world. He runs a company called Like Store, which aims to enhance the online reputations of companies.
Center to his business model is a feature which promises to give Facebook users free content for clicking the "Like" button on his clients' Facebook pages.
Facebook has been in contact with Zuckerberg, Zuckerberg says. But not about the legality of his name but instead about his business since it violates Facebook's terms of service.
