Then why is there a 1:1 copy of most of the Facebook signup page in the facebook subfolder?
The suspension reason indicates part of it was for "masquerading as a trustworthy entity." You are not Facebook, and therefore shouldn't be having all of facebooks signup page in there. You can call it a number of different things, but if it's not phishing, then it's copyright and trademark infringement as I'm sure they would -not- approve of the unauthorised copying and uploading of their entire page and source code without their express written permission.
