Well, after using digitalpoint for a while, I realized that their iTrader is step up differently in which you have to supply a deal thread URL. I just think its a good way to bring about legitmacy, and the mods can do random sweeps?
If you think a rating is a fraud you can use the report button. Not all my deals with a tf member had a thread, so if I talked to a TF member and did the job just on msn id be out of luck
