What's to stop a single unlimited user from generating and sharing infinite tokens with the rest of the world, then?

Edit: Each account is limited to 2000 tokens per month, unless they email support to request more. (from the FAQ near the bottom).

Still seems like there could be a secondary market for resold tokens, though. Not just as a money making system, but possibly as a privacy initiative? If enough accounts pooled tokens into a shared pool and withdrew a random one from it each time, it would be a further safeguard.
