I don't think that will take you anywhere, a freeloader is a freeloader and a paying member is a paying member, i think you'll just upset the paying members and the freeloaders will just go away, which is not a bad thing, but they sometimes entertain the models.
I might be wrong, but i don't see how that will land you on the Moon. Just offer some nice big discounts to get the site started, come up with promotions both for members and models or even studios. Offer members something extra for their bucks, free videos, X amount of free credits on each X amount of credit purchase or whatever, you understand what i mean.
Nobody cares that much about anything else but price and models and a user friendly site.
