Oh yeah, and I know tons of people on there under their SCA names. I think the policy is a holdover from the early days of Facebook, when you had to have a college email address and your name had to match it--as I said, it's not enforced MUCH now due to scale, but there are still some nasty episodes, often with people whose names look "funny" (=non-European) or whose names happen to match with a celebrity.

Owl Goingback is an example of the former.

Policies like that are always incredibly random unless they require some kind of ID upon signup--and the people who get targeted are disproportionately those with non-European or otherwise "weird" names.
