I did, no particular topic, just generally a lot (think "my comment history minus biting my tongue"), and a few years ago, after 9 years of using it and 100+ RL friends and plenty RL photos, I could no longer log in and was asked to send a copy of my ID, because I might not be a real person. I didn't, not because I think anything in that scan would be new information to them, but as a matter of principle, out of sheer stubborness and a sense of injustice -- they didn't tell me who reported me as not being a person, and I bet you none of the accusers had to show their ID.
But being "banned" from FB is much better than quitting... I have zero temptation to go back, it requires no discipline at all, so I'm not complaining.
So then you just created this account to tell us that Facebook banned you for no reason even though you posted nothing? Interesting, why did you do that?
