Why doesn't stunna publish a list of Hufflepuff's PrimeDice alts so we can see if any of them match any forum handles?
That would probably not do any good. Even if he was using any of the alts, the chances of his identity being known through any of his accounts is very less. And even if does become known, there would be nothing Stunna would be able to do against him. Specially when there is not legal help that he will get.
I don't see any downside to releasing the alts. If/when their RL identity is discovered then stunna could sue them to recover damages for the Bitcoin he stole.
I believe Stunna has been researching all of this as well as he will not let this things go away since he knew that hufflepuff cheated. He had promised to release a full details on how hufflepuff did the exploit as well as the other things in article but until now the promise isnt fullfill yet.
Mostly I believe the reason for the delay is because Stunna is investigating this deeper and would not want hufflepuff to know that he is being investigated right now
if you are interested perhaps you can track on this
