It would by cool if only the creator of the topic can see the answers. Sometimes u make a topic and go to work and when u come back the person dont have the item becous people sniped.

sounds like a great way to price fix

"this other guy offer 500 more than you did, just trust me dude"

Trade snipers are scum
I usually offer my items slightly below the market value because I hate trading and haggling and shit so I want it to be quick, and people always try to snipe. Like someone is looking for a Czako and I offer mine for cheap in their thread, and I get PM's from other irrelevant people trying to steal the deal
No matter how much they offer I just ignore them / waste their time because:
1- I don't want this behavior to be encouraged
2- I don't want to make a trade sniper happy

That's just how cool I am
