Here's an interesting entry in shotev's post history (translation follows)...
So it seems that this user might have been used unwittingly, and he is not the real culprit behind this scheme (or scam, lol)
This is only a manipulation...
Also try to translate the last post of bitevil. It looks like he's the only one who received a payment from the mixer.

at least someone gets paid :DDDD
The last post of bitevil (with translation):
Hy я зaбaxл мнe пpишли пpaвдa c 3-4ч зaдepжкoй нo вpoдe вce нopм
Well, I threw [some coins] in and I got them back, after a 3 to 4 hour delay, though. Everything kinda seems to be okay
He tried mixing his coins and got them back after a few hour delay. Whether he has been paid remains unknown
