Okay, here is the thing --
1. It is utopianfuture's policy not to reply anyone in PM.
2. I have concrete evidence that would lead to discover of big multi-accounters. However, it would require some investigative work. I cannot do it alone so I am asking for help.
3. I have some of sellingallmynem's accounts. By tracing them and combining what he told me during our course of conversation, I was able to discover his identity.
4. Has anyone considered the possibility that what I'm telling you is the truth? So nobody cared? So be it.
I reply to a lot of PM but I don't deal with stake issue via PM. I suggest you to publish all of your finding in the stake complaint thread. Everyone including me could use your finding if they are useful and at the same time can validate the contents of your finding.
I don't see the need to form a NEM KGB to deal with your concern (or any other one for that matter).
