On the legal issues - I could maybe see a point, but I understand these are archived discussions, probably too late to read info about an ongoing case? Most of the actually complaints cited are already onling, so no secret there.
Appraisals? I don't see the issue. It's been pointed out many times here that they're usually WAY off the mark when it comes to final sale. As far as I know, many people making appraisals have never sold a domain name in their lives, in fact I've seen appraisals here from people who admit that. Are you all going to stop selling your used cars because the Kelly Blue Book (which IS professional and very tried to reality) is available online for free? Of course not. A better analogy would be real estate - any potential buyer can 1) Look up previous sales prices and 2) hire his own appraiser... does this stop real estate sales? NOPE. In fact real estate prices have doubled over the last few years.
Again - most end users I see ASSUME I paid $10 for it, and have never even heard the term "dropped domain". The name is worth what the buyer is willing to pay for it, period. Those who are doing all kinds of research and are so concerned about what your cost was are likely to be other resellers who already have a potential buyer, and are just trying to bargain you down to get a better margin for themselves. Again, I don't care... we'll either agree on a price and a deal will be make, or I'll wait for the next buyer. Same goes with the stories about "I'm a student working on a class project", "My wife wants to start a business and has no money", "My dog ate my family", etc. etc. etc.
