Facebook Ban

I opened an account for my site on Facebook with an email ID in hotmail which have only alphabets in the front. After about 3 weeks ,Facebook blocked my account and keeps asking to identify some photographs which i have not seen also. What could be the reason and how to open my account.

As far as I know If you can't identify those images then you will need to contact them to step in.

Why don't you create another account with gmail or yahoo address? I know that you can't even register on some forums with a hotmail email address.
