Facebook Identity Question?

[RinMichaelisElric]

I have this facebook account and I made it a few days ago. It was fine last night when I logged off, and then when I logged in this morning, I guess I was locked out and they wouldn't let me in without taking one of those identify your friends security check things. I keep failing them cause I don't personally know all the friends on that account. And now, they don't give me options of names like they used to, I have to type the name myself.
Anyway, the purpose of this is that it says "hourly limit exceeded"
How long until I can do the security checks again? Cause I completely miss my account T-T
