Why on earth would you want this?

A seller sends a faulty item, doesn't respond to messages and/or refuses to resolve the problem with the buyer (whose money by the way sellers rely on) and the buyer leaves a negative - and, according to your protocol can't buy again.?

Madness.

Feedback BTW is voluntary, and if you have these TOS in place, any FB you get sure ain't going to be positive.
