fake facebook accounts?

[lisa]

If fb find out you have made a account that's fake what are they likely to do

block your account will this be permanently or just for a short time, and will they block your real account, and are they likely to block your ip or would this be last option like if you keep breaking the rules and will they email u before doing anything.
Fb will know this a fake because I reported it as my old account so they will no by names etc. Am I in trouble will they ban me can the police get involved I reported it cause I wanted it delted but lost the details. I did do anything bad.
