Took the words right out of my mouth, not sure why anyone would pay money when there are (apparently) loads of free sites out there. Although presumably there must be a fair few paying for access judging by the amount of pay sites on the worldwide web. Noticed a few porn related ICOs towards the end of last year, and even more over the last six months. Must be more lucrative than I thought, although I can definitely see the benefits of anonymous payments if someone was so inclined.
