Years ago, eBay made it more difficult to sell pornographic magazines through their site and competitors such as naughtybids.com cropped up. Similarly, Stormpay and other methods of purchasing adult magazines online were in action for a time.
Eventually, eBay and Paypal got with the program, slowly enabling such auctions again. The competing services went out of business not long after.
I'm guessing that other online venues will come in to attempt filling the void, though this push towards abstract censorship of adult materials - for adults - continues a troubling trend we've been seeing the past decade or so.
