What's the difference between ProAdult sites and Quantum sites?

ProAdult Quantum is a showcase of sites that have at least 5 times the amount of content that regular ProAdult sites do. They undergo tedious reviews and must meet higher standards then the regular ProAdult sites. Also, with your Quantum ID you get access to our Quantum Members area which is updated daily as a bonus for your monthly membership.

The regular ProAdult sites billing cycle is an annual fee of $24.95 whereas the Quantum program is a monthly billing cycle at $23.95 because of the difference in the amount of content that is offered.
