Just make sure you don't hotlink images. I saw someone through a friend of mine update their images to pr0n and switch the urls for their pages. Was quite funny, and got the one stealing the images a nice ban.
Also, are you including your own code, or just a rip off another site with a few touches to make sure it works perfect?
Lastly, the become a fan feature, do you have a working in-page become a fan button, or does it direct them to the top of the page?
