Going to try this again. With all the issues regarding appropriate listings, too many listings, rediculous listing, endless post bumping, I'm going to try a new approach.
Your account has credits tied to it now. I set everyone up with a freebie to start things off. You can use the credits to list something. Extra credits can be purchased for 1USD via paypal. Right now it's manual (you send, and I get a PM, then I check and update your account), but I hope to automate it more. Don't want to invest the time if this seems to not work though.
So basically if you want to bump a post, feel free, it'll cost a buck. If you want to list a pair for retail or for a price no one will ever pay, it'll cost a buck. This pretty much leaves the moderating out, since if you feel you want to use the credit, there won't be any objection. It's low enough (compared to ebay), and after PP fees, it's not like any of it really makes a difference. All fees will go to hosting costs, which up to now have been taken care of out-of-pocket.
Hopefully this will be a good solution, since many want the system, but I don't like dealing with the drama and whatnot that comes with it.
Let me know what you think. There's also a feedback system and and a reservation system, so you can call dibs. Here's how it goes.
Seller lists item.
Buyer likes item, so he reserves it, and is redirected directly to the PM screen.
Item is changed to 'Pending'
Seller receives PM and either decides to sell or not sell.
If he/she sells, he/she marks the item as sold. If not sold, the flag is reset as available.
Once the item is set as Sold, both sides can then mark it as a favorable or unfavorable transaction, which will then show on the auction listing.
