Same. I'm not saying op is a scammer but I never understand why people want to do this for free even just to build feedback as it seems like a major hassle, and of course scammers also try use this as a long con... do a few small trades then run off as soon as they get a decent amount. I'd try build up trust doing other trades, offering escrow definitly isn't the way to do this.
I do it for free because I honestly want to help out the community. It pisses me off (escuse my attitude) when i see potential scammers trying to work their magic on other, innocent people. Without escrows, a lot of trades wouldn't have been successful because no parties would fully trust each other. With an escrow, its not 100% scam proof, but it'll be a lot harder for any party to scam the other. Why doesn't the escrow just take the money and run? some will, and some have. But for me... Firstly, ive spent well over a year building up my reputation, and scamming is just not the way to go IMHO. Also, I honestly believe in karma... And this action would be morally incorrect and I'll probably regret it for quite sometime! So yeah, 100% secure escrow
But in all seriousness, that's why I offer free escrow services. This community helped me get started and I'm just returning the favour!
