Sigh, you people are missing the point. I misunderstood what his original point was, but he's still recommending actions that are illegal around here. Even under the most rosy of interpretations you're still looking at about a half dozen civil infrations which could and would be used in his defense if things get to court.
I see that the fact that eBay's policies are so horribly broken in favor of the people buying products isn't a problem? That's sort of the point, when you allow people to renegotiate the terms of the contract after the fact. Deprive the seller of selling to somebody that's actually going to pay for it, it's harmful to the economy as well. There's a reason why tortious interference isn't legally permissible.
As I've said before the situation sucks for everybody as well, but advocating for fraud isn't going to help anybody out. Regardless of whether or not it rises to the level of a felony, it's still something that can and will show up in the public record and potentially be shown to potential employers. All it's going to do is make a relatively simple case much more complex and greatly increase the cost of litigating it if it comes to that.
