My FB account is scheduled for deletion. But wtf it was a hack to disconnect all my devices, apps, and other accounts. I kept the account open just because I (thought I) need the API-key for omniAuth. Since FB is such a waste of time, even if you visit your page rarely, I decide it's not worth to keep it. There are a lot of alternatives to be used for oAuth and I can waive FB and never will miss it.
