Imagine that you post a thread in the WTB section. You get messages from members offering the service. Imagine that those members are not offering the service in the BST section. What would you do? Ask them to offer the service in the BST section? Is that enough? What if the member uses the BST section and ends being a scammer? Is it ok to ask a mod to operate as a tester or escrow service? What are your opinions? Edit: I will add this question. When should you report a member as a scammer? Only after being scammed?
