Thank for that list, it's a great overview!
I think the GLBSE-founder Nefario (

Unfortunately the list of scammers not YET sentenced is way way longer. I hope we can work on bringing those to the same place soon. Unfortunately i dont see many users going behind the ones. Most only cry, extort or threaten. Not many put the time into it that is needed to first find the problem and then trying to solve or enforce prosecution.
Indeed. It seems authorities are primarily focusing on enforcing their freedom-hostile regulatory frameworks instead of persecuting actual criminals.
