Ask for a PM, solves all problems.
If they refuse, do not trade with them.
Very well said, Masterkiller..
Greating a thread/sticky of all imposters are pointless, but once there is an imposter its usually cought on very quickyl and posted, thus allowing the real person being informed and then knowing.
Then on their main thread they will show what their imposters addy is.
So, I find this suggestion pointless.. If you don't ask for a PM, and you don't make sure it's the correct individual or anything. Then that's your fault..
When I conduct a trade etc..
I,
1.) Request PM.
2.) *If not same, but get the PM*
3.) Request another PM regaurding the deal, as well as sending a link to the thread of which hes wanting to buy, the MSN he is currently using to conduct the deal.
4.) Request him to post on the thread the same as my request for the PM other than the link.
