I saw that on the TV a couple of months ago. Actually, he collected many yearbooks at the college's library without a permission. He did not have the authorization to do that, but somehow he did it all the work and put them on his website. That's how he started his Facebook business.
Generally, Bill Gate gave him some millions of dollars to support his company.
Now, I think that Mark will be in a big trouble with the law because of one main reason that those people in the yearbook did not ask him to put their portrait on his website for a security reason. That's his grave mistake.
On other side for Bill Gate, he did not care about that because he is not involved in Mark's business. Just because Mark is very young so Bill was also young as a troubled kid at school. Bill's personal way that he likes to help young people who are under 21 years old and they have a website business. You will see his way on the news once a while.
Mark knew that he was wrong at the being, but he wanted to do it on his purpose in order to make money. I think that he is just a sick young man as a peeper. I don't hate him. He is just doing very wrong thing to do.
