For nothing you get blurred photos, messages unable to be read, and lots of notifications about how interested all these gorgeous girls are in you. In other words you get nothing but frustration for nothing, I think at least a few days of messages and photos for free would be a better business idea, so if you want to continue with someone you find you'll then pay, my experience with these sites is that their goal is $$$ using our needs as bait.
Pros
none
Cons
too hard to get any communication at all without paying for "premium".
