They only crack down on accounts that have been reported by other Facebook users. So it's usually not a problem if you're not abusing the anonymity. Obviously there are minority groups who are more at risk of being maliciously reported, and it looks like that's the change here.

This is incorrect for some communities, I have a lot of friends who are furries and their accounts get banned for not having real names all the time. For example, my Epoch Wolf account got banned years ago.
