Look the Trades and Wants section has been here long before any of the so called "Scammers" We shouldn't remove it just because some members have been too naive to not think before they send people money. 99% of the members on here can be trusted but we only here about the bad ones.
It's all about common sense really. If you can't find someone on here who is a long standing member with a good reputation, then look on eBay. Don't send your hard earned cash to someone on here if they are not reputable or less than a year old with less than 250 posts. Lets not forget this is also the "Trades and Wants", not the eBay section. List an item and name your asking price. Stop asking for people to make offers, we all know roughly how much we would like to get for our items so be fair.
Sorry for the rant, but I am sick of hearing about members being ripped off by other members on here. It makes the whole community look bad.
