I believe a new rule should be in place when dealing with violations in the sale section.
if a trade has clearly taken place and money has passed hands but a mod sees the sale as worthy of an infraction or suspension then this should be done AFTER the deal has been finalised with the buyer.
The mods should contact the buyer, explain to them that they must let them know when they receive the item and are happy. Then they can pursue the seller and take any action.
I believe that suspending a seller immediately after they have been paid a wad of money could disgruntle them and lead to them doing a disappearing act.
It can happen, some members may get peed off, especially if they only have a few feedback and a fairly new member.
There is no harm in letting the deal complete then taking action, it is safer for the buyer, after all they need protecting in these circumstances and suspending members while they have another members money is not the correct way to go about things.
Your thought son this matter?
A simple rule to rewrite and put into action if the mods/admin would look into it.
