That may be true also, have you ever seen bodybuilded dude with huge gang as a hacker? His phisycal condition is probably really really poor and judging by that ammount of time he wants between these transactions he clearly left some traces in dropbox, someone should make the dropbox developers give us the IP.
No offense, but I fail to see what his physical abilities have to do with his hacking abilities (if it is even a he). Not trying to be a big downer, but to be brutally honest if you were to go via the criminal justice system your case would probably collapse if you didn't have much more information than his IP to prove that he did it. From what I've read (and learnt), judges don't really believe that an IP equates to a specific person (as piracy cases will show you). How would you even prove he stole it, although unlikely, he could claim that it was transferred by klee to him for some unbeknownst reason? And how would you know you had the right guy, unless you managed to get a warrant for police to raid his equipment?
Or would you just take the more dangerous and possibly convenient route and hire someone to scare him/worse? And even worse, what happens if you get the wrong guy?
I'm pointing on that that klee accepted his defeat as he is worried about his fammily, he claimed that in another thread wich i'm currently not sure about wich one it was.
