outgame walker was very risky even back in the days on ncwest 2005, i don't think it will be much harder to detect now... but yea. i'm suprised they're making more money than the electricity bill for that stuff. maybe power doesn't cost anything in china.
there is some cities in china and so on where botters and bitcoin mining industries get lower price for electricity+ they choose cold places with low humidity so they use even lower power. obviously, it's not the same farming bitcoins than farming adensky...
