If, as you say, the mods have no time or interest in looking at this, shouldn't they apply for help or step back?
We have, theymos even posted a thread about it once. A couple people got all gung ho about it, but it didn't go anywhere. Turns out people don't want to spend their free time doing that. Go figure

https://bitcointalk.org/index.php?topic=90953.0Most of us would be more than happy to have nothing at all to do with scammer tags. It's essentially a free service provided by the forum to try to help and pretty much the only thing gotten in return is complaining, trolling, accusations (no matter which way the decision goes), drama, etc. Someone gets the tag, well clearly it's because he ripped off staff. Someone doesn't get the tag, well clearly it's because staff is in on it. I do try and weigh in on high profile stuff, but that's about it. Too much hassle and grief to do anything more.
Got it, thanks for the link and response.
I'll let it rest for now because I have more productive work to do and because evidence is building up that he has mental issues (either that or he is faking it very well and is in fact a masochistic drama queen). If he does have delusional disorder, I have to think about how to proceed. I started taking an interest in usagi, because he has caused me damage in the past and is impossible to reason with. Then I noticed he is doing the same to many. Apart from some pathetic scam accusation threads he created the situation is contained for now. However if usagi tries to pull off another scammy business in the future, I'm sure I'll be all over it again. I would consider paying someone who is specializing in independent scam investigations as theymos proposed in that post. We'll see what happens next.
