How exactly could we fight this problems with the high level of anonymousness intrinsic in the crypto world? I mean we can report scams and so on..but hardly catch or blacklist somehow the bad guys ..
I agree there are challenges with such work. However, it has been done before and even though people can remain anonymous and never get caught the fact is that we are all human and frequently make mistakes. Also, people that specialize in investigating cyber crimes have experience that you and I don't have. All that's missing is a way to finance these folks so that they can put their skills to good use.
And that's really the point of this discussion. I don't want to argue about the ability or inability of cyber sleuths to catch criminals. We have already seen a suspect in custody from the Mt Gox heist and other criminals have been caught.
This effort will not end crime but it could bring about a method to finance a justice system without being taxed directly. Of course I add the "directly" caveat because ultimately we pay something rather it be a tax or a premium for some "justice coin" that could finance investigations.
I'm thinking of tiered rewards and community votes for how much compensation should go to successful detectives. Of course, compensation would have to be paid in accordance with the criminal actually being found guilty in some court but at least maybe the first layers of justice (investigation) could be financed without taxes. The next interesting part would be to figure out what to do with the suspects once they are identified. Many places have law enforcement offices that include cyber crimes divisions so most of us are already paying taxes for that.
