Anyone who clicks agree without reading and carefully interpreting every word of the terms of service is in fact consenting to almost anything. Almost anything you can think of could be there and you don't care.

I mean even things which are not actually written in the TOS. If you don't know what's in the agreement, you're agreeing to almost anything in principle.

The number of Facebook users who have actually read all the legal crap probably wouldn't fill a small lecture hall.
