I deactivated my genuine facebook because I am still totally angry at facebook rules and regulations.
In my opinion, facebook is a place to share photos, news and ideas, not a place to see who is now friends with who. I have been warned for posting too much on facebook for many times. Go figure. There are millions of fake profiles out there. Facebook team do not disable those accounts, but disable the real accounts. And the worst thing is now that if they disable your account, you cannot appeal to reinstate your account. The account I used to play games on facebook was disabled weeks ago. I tried to appeal but they said "the decision is final. No appeal would be entertained" WTF? I've been using that account to play games for more than a year, and have earned certain levels there.
Anyway, I really enjoyed my time there. Now I get more time to study and have time for myself.
