Mr Dank started a thread and I responded, however it's still last night for me and I can't find it, but I linked to where SR explained how it works.More weight is given to buyers who buy from a wide variety of vendors, and higher priced items. Lots of feedback for low amounts may fill the slots, but won't send a vendor up the ranks. It's pretty well thought out and hard to game, and I'm sure it's also like Googles search algorithms, constantly in a state of flux.Multiple ratings from a buyer who doesn't also deal with multiple vendors carry less weight, as do low cost purchases.Except for Mr Dank, I don't think anyone here, once they actually read and study how it's done now, thinks the system is being abused. 5 point feedbacks for finalizing early definitely is a prob, as it's been used by every vendor here who's done a big rip-off and runner.mseller just posted a thread with a good solution to that in this forum.
