Hijacking others' hardware and stealing their electricity is fine for you? And doing that in order to steal boatloads of blocks from legit miners?
The guy is a fucking criminal that should be lynched a.s.a.p.
So having a large hashrate is a crime now? Last I heard people are innocent until proven guilty, finding out if he is breaking the law is someone else's job, and finding out the details of their finances is for them to do. That said, sure he's probably running a botnet, so send a letter about it to the appropriate legal agency if you want to do something about it. Doesn't mean you can violate his privacy.
