Hmmmmm...Yah seems to be like the whole community is in disarray of trust.  Maybe there should be a protocol that the moderators of this sub forum should police.  I think decadentmining has a point of the pics and documented process of a transaction.

1) Prior to any transaction the seller who posts needs to put a picture up with item and forum name handle.  If pics aren't put up with name then post should be taken off by the moderators.
2) Within the same thread some way of documenting money sent from buyer and shipment label with posted date.
3) When buyer receives the item, they can take a picture with name and also post on the same thread to complete the transaction.

Not sure if this will a sure shot way but at least there's a trail and its a little safer?

Thoughts?
