I cannot locate a forum rule that imposes an escrow service on the auctions here. Would you kindly provide the URL to this rule?
Try applying common sense, would you send 5
BTC + to a complete stranger that has zero trade history, no transaction feedback and only joined a few hours ago on a promise they will send you an oz of gold.
Escrow providers like Tomatocage, OgNasty etc. are trustworthy and have handled $100k's worth of Escrow previously. This provides buyer and seller protection
+ will help you achieve the best price for your goods.
