SpankChain is a very sensible layer on top of Ethereum, allowing workers to bring their reputation and fanbase with them across services and avoid lock-in. This is exactly the kind of thing that makes sense to build on top of Ethereum.
I wish them luck and hope they solve payment processing problems for adult performers once and for all. That said, the only point of a separate token I see is getting them money so they can actually implement the system. From end users' point of view it would be easier if ETH was used directly imho.
