Quoted from Whysnow:my fbook account is real and my real name. Tell the loser he is wrong when you talk to him next.
"Nicknames can be used as a first or middle name if they're a variation of your authentic name"
There is not a second side to this story. The creeper/stalker has set up a Fbook account impersonating me and has called to try and messed with my job. It is pretty clear that this is not even remotely appropriate behavior.
Again, don't know the guy. You asked for people's opinions regarding this situation and I'm giving my uninformed one.
If you were to actually read the link I posted, you would see that you are indeed in violation of Facebook's policies as well with your Facebook name as the nickname Miguel likely does not appear on official acceptable documentation
