Mark Elliot Zuckerberg

In June 2010, Pakistani Deputy Attorney General Muhammad Azhar Sidiqque launched a criminal investigation into Zuckerberg and Facebook co-founders Dustin Moskovitz and Chris Hughes after a "Draw Muhammad" contest was hosted on Facebook. The investigation also named the anonymous German woman who created the contest. Sidiqque asked the country's police to contact Interpol to have Zuckerberg and the three others arrested for blasphemy. On May 19, 2010, Facebook's website was temporarily blocked in Pakistan until Facebook removed the contest from its website at the end of May. Sidiqque also asked its UN representative to raise the issue with the United Nations General Assembly.

On June 30, 2010, Paul Ceglia, the owner of a wood pellet fuel company in Allegany County, upstate New York, filed a lawsuit against Zuckerberg, claiming 84% ownership of Facebook and seeking monetary damages. According to Ceglia, he and Zuckerberg signed a contract on April 28, 2003 that an initial fee of $1,000 entitled Ceglia to 50% of the website's revenue, as well as an additional 1% interest in the business per day after January 1, 2004, until website completion. Zuckerberg was developing other projects at the time, among which was Facemash, the predecessor of Facebook, but did not register the domain name thefacebook.com until January 1, 2004. Facebook management dismissed the lawsuit as "completely frivolous". Facebook spokesman Barry Schnitt told a reporter that Ceglia's counsel had unsuccessfully sought an out-of-court settlement.
The contract itself says that Ceglia agreed to pay Zuckerberg $1,000 for StreetFax and $1,000 for another project called PageBook. The contract also mentions an expanded project called The Face Book to be completed by January 2004, saying “an additional 1% interest in the business will be due the buyer for each day the website is delayed from that date”. Ceglia has proffered a $1,000 receipt from his checkbook, dated six months after the contract as evidence that he paid Zuckerberg for his work. But it wasn't the full $2,000 amount, and the agreement doesn’t describe what happens if there is a default.
