Can Facebook be considered a unofficial dating site?

Honey, people try to use LinkedIn for dating.

I have a pit dug at the end of my garden which I check daily, those who aren't dating material soon get released.

Gotta keep that stock rotated.

I have a healthy turnover.

One of my old friends from World of Warcraft logged in the game recently, and I found out that he married a girl from our old guild.

Personally I would not see it that way. I stopped using it completely over six months ago, not that I was using it to date anyway. If something comes from it that way all well & good but personally I would not use it that way. To many scammers out there! Me I am completely done with dating anyone, got burned so many times , I trust no-one anymore, getting to old to be messed around with!! The only person you can trust is yourself!!
