What CAN'T I include on the page my FB ads point to?

Hi there! I can't seem to find a list of dos and donts for what to include on my squeeze/ landing page that I point to from FB. Adwords/ POF have specific non-categorical guidelines, like a minimum amount of content (adwords doesn't like simply a squeeze page anymore) or number of links vs. content.

I know that on Facebook, a page cannot prevent a user from exiting/ backspacing in one click, and that there are many topics that aren't ok -- but does anyone know what I should or shouldn't point to to ensure my account doesn't get banned?

Thanks all!
