I own pandorasbrain.com and want to sell it. Every couple months I get an "offer" for a few thousand dollars, and every time I say yes -- which inevitably leads to the other person replying "actually I don't have the money right now, would you sell it to me for [$100, $200, maybe $400]". ... which I also say yes to! ... and then they disappear and never respond.
I have no idea what this presumed scam is about, but rest assured there are people out here with .coms who want to sell for much less than $10k, but ... nobody's interested!
