I got flagged on Facebook for using an obviously fake name. So I changed to a more plausible sounding name and it worked. I had prepared a doctored passport scan but it wasn't necessary.

For another FB account they wanted me to get at least two user friends to verify they know me or some bs like that. I didn't bother. Years later I was able to log into that one anyhow.

They know that they can't push too hard.
