It is a very tricky subject.
With a vendor, there are MANY options to resolve the issue, personally, before coming to a public forum and criticizing their response to a particular situation. All options would have to have been 100% exhausted before I could reasonably allow a negative posting to be made.
For a seller, it is strongly recommended that the ONLY payment option is through PAYPAL GOODs, which PAYPAL protects. If an issue were to arise, it could be handled confidentially and personally through PayPal. I will be the first one to tell you, if you paid by cash, check, or any other option through paypal that was not the goods option, that you are a complete tit and it's your own damn fault.
I fully agree with a name and shame, but some people are quick to post in their anger and it can spiral out of control very quickly. This is something that will have to be talked over with the Admin team. For right now, I think most of us are pretty acceptable of a lot of things.
One thing is certain, we do NOT want this to become a negative forum, nor do we want to allow situations that could open the possibility of repeat recent mistakes.
