Hi. I like porn. Alot of people like porn. Alot of people have wives that stay at home and can't wait for your credit card statement to come in via snail mail so they can open it and catch you red-handed with "shady" charges on your card.

As far as a "for profit" business model based around BTC goes...?

Offer a service that will pay subscription based fees on the behalf of the Bitcoin sender. Subscriptions to Porn sites, subscriptions to MMORPGs like WoW, etc... things people don't want to show up on their credit card statements for whatever reason. This seems like it'd be viable simply because part of the beauty of BTC is the anonymity that comes along with it. A bitcoin related service that supports this anonymity would be quite popular I imagine.

In essence, it would just serve as a payment proxy. Let's say "Client X" wants to purchase a 3 month membership to Brazzers, a porn site, for $59.97, which is the actual price. Client X then sends you the equivalent in Bitcoins, roughly 6 coins at current value(plus a small fee, say 1%), and then you charge the $59.97 to your debit/credit card and hand over the login info. You get paid for providing the service of true anonymity, and your client is happy that no paper trail will ever rear its ugly head. I suppose the same could be accomplished by purchasing a pre-paid Visa card.. hmm.....

Anyway, I'm not interested in starting up a business like this, but I think there's a market for it, especially in countries that don't have pre-paid plastic.
