So basically this just begs for the owners to create two clearly differentiated brands: (1) the current one will probably die like Tumblr but they have some high-profile non-porn creators so I think they will keep going for a while, (2) the second one geared towards porn mainly and accepting alternative payment methods like Webmoney, Paysafecard and others. They can start accepting credit cards and Paypal initially to gain users, and when the pressure builds up, drop the banks and hope that the users are so attached to their content they'll use the alternative methods.
