What's to stop this from getting abused, though? What verifies that a deal actually took place?
At the risk of being labeled too trusting and naive, I would hope common sense and courtesy would prevent abuse.
The community here is much tighter than ebay and therefore, there's a higher level of accountability for both sellers and buyers. Also here, in the event of unwarranted and/or malicious retaliatory feedback, we can discuss the problems openly and let people decide on their own based on full explanations rather than 80 spaces for feedback comments and responses.
And unlike ebay there are more than commercial reasons for being here. If we want to remain a welcome part of the n-g.com community, we should not abuse each other nor should we abuse the useful features provided for our convenience.
