There have been real buyers in domains wanted,
@bmugford has made real posts and purchased names. He does not anymore because people don't seem to understand. Looking for .com only does not mean "Hey bro I know you said .com only but this is a really great .fyi and I would know great because I have been in this business in a whole 3 months.
Many buyers with big budgets are looking to see what you got, email Brent Oxley and say Brent this guy will sell Brad.com for $200,000. You interested? No, counter at $75,000 etc... So they can show Brent names and if on the off chance he buys one, they get paid 10% from Brent on the purchase price. If he says no, they do not reply and you have no idea who they are in real life. Last time I chatted with Brent I think we discussed the number might be 100 people worldwide try to earn a living off Brent, sometimes 30 people will send him the same name, all at different prices sometimes.
