There would be nothing stopping NavySeal selling the items multiple times via PM. The only thing about the forum sales,is that people showing "interest" would have posted on the site. Once contacted by PM, he could sell it to everyone showing interest. No different to the multiple sales of the classifieds.
The issue is not the system here but the person(s).
EG.
Forum post by seller.
Couple of replies by buyer 1, buyer 2 and buyer 3.
PM's sent by each buyer.
PM from seller to buyer 1 saying they can buy it, arrange payment etc.
PM from seller to buyer 2,saying still available, arrange to sell, payment etc
PM from seller to buyer 3,saying still available and arrange to sell once again
Forum advert would read SOLD next to the item. But still 3 people have paid for the one item!
So to me, i cant see the difference? Because I would never arrange payment etc on the public forum as this is private information.
I didn't start this thread to try and cause an argument, it was simply to highlight a weakness in the system, which whether anyone wants to admit it or not exists
The old system was a lot more public, even if you weren't the buyer of the item you may know the person who had bought it.
ie
I buy a set of cooper brakes off Pie, I then go and tell a few mates via pm that I've done so.
Roofless is on on during the day and sees a conversation between pie and and another buyer, he alerts me and that arouses suspicion
If you look the old for sale threads people who buy items, usually post up with "Sold to me!" or similar.
This would then pop up at the top of the new posts list.
Also as the ads didn't have a finate life they could be used to keep track of when the items had been posted therefore if 3 people pop up all asking where their set of cooper brakes is then that gave an early warning as well.
A scammer will always try to find a way to rip people off, however the more public the transaction the more chance they have of being caught, at the moment the for sale area is a dingy little backroom away from the main area.
Some forums encourage deals to be done in public rather than via pm, again this gives everyone protection. In this instance if the seller decided to conduct buisness in private that would start alarm bell ringings, if you got nothing to hide then do in it full view of everyone.
I don't for one minute expect a sudden u-turn and undo the all the hard work that has gone into the new system, however improvements and upgrades have been promised for a while now and nothing seems to have been done.
Buying and selling on this forum used to be easy, I've always put full trust in anyone I'm buying and selling to on the forum and so far have never been let down.
Simply saying that there isn't a problem with the system doesn't really help anyone, as far as I can see there is a very big weak spot that needs to addressed before it happens again.
