I have, several times. I'm currently in Facebook Jail for having posted a link to When The Bedbugs Bite: Bite Back.
I tried to appeal their decision but as is most often the case my effort only resulted in the following:
They didn't even tell me what rule I had broken, only that I had violated community standards.
On one such occasion I was put in Facebook Jail and won my appeal... 30 days after I got out of jail.
I don't know how many of the claims made in the USA Today article Facebook while black are really true but what is true is that Facebook's system of moderation, reporting, and appeal is broken.
