Yep someone complained that I called someone as dumb as a box of rocks and that was enough to warrant a ban. But yes, there are pages which propagate racism and sexually explicit stuff which are considered to be protected free speech by Facebook. Hey I'm into free speech too - so let me call people as dumb as rocks as and when I see fit! If someone called me dumb (which happens, hard to believe I know....) I just can't imagine being so upset that I complained to a higher authority.
