FB name verification

[MindfulBear]

Why oh why does FB want to verify my name? A name I have been using for ages on FB in fact. I have tweaked my surname so people can't find me. However it is sufficiently similar to my name that you would not be confused.
Anyone else experienced this? I don't want to use my real surname on FB so why should they force me too? Will this mean my account is locked out forever ?
