Hypothetical question: if someone did this more than once and received negative feedback, would they be banned?
Seems like I've seen a lot of welching going on lately.
I dont think you can give negative feedback under this scenario because a deal has not been set as defined in the forum rules.
EDIT: and I dont think negative feedback gets you banned. Scammers get banned, but not flakes. SOmeone correct me if I am wrong.
