I would not pay that to get rid of ads. However, ads don't bother me. The "social placement" advertising that (ab)uses my friend's content to turn them into shills is what I find a significant turnoff, combined with the other invasive and slimy methods of data collection mentioned elsewhere in this thread.

I don't care if Facebook does advertising. However, the slimy methods used burn any trust I have in them, and as a result, I'm not going to hand them any extra data if I can avoid it.
