The contracts between users are all cryptographically signed in a system called Ricardian Contracts. At any point each party has a digitally signed copy of all the information they need to proceed with the trade.
Because this is a protocol for decentralized trade, and a network to engage in trade, there's really no terms of service or privacy policies that can be enforced between users. They connect to each other completely P2P, the devs or anyone else can't enforce anything between them (and don't even know a transaction is happening).
Is this a sorta "we had no idea so much of our revenue was derived from pirated content" play sorta like Youtube, then, but for an active marketplace that's actually maybe just filled with fraud?
No awareness by the company and no easy ability to enforce terms before users make me wonder why the heck I'd ever want to try to sell or buy something on that platform. Seems like craigslist but with too high a bar of entry for the good-intentioned non-fraudster non-tech-savvy users.
