Was there more than one case? Can you back this up? I have read previous incident, but I didn't find any other. I am not very active in 'Scam Accusations' board now. I could have missed it if there was any.
There was a case against defcon23 that wasn't really anything, mainly just defcon and Quickseller coming together to mutually talk bad of the incident. It's also important to note that both defcon and Quickseller are blackmailers/extortionists themselves, so it is the pots calling the kettle black at best.
I also think you may have been around for it, however I may be wrong -
