After consulting with minerpart I will report these threats to blackmail and extort money from companies on Bitcointalk to an FBI Field Office.
We believe a crime has already been committed, but if this poster actually proceeds to Troll because no money has been paid to him, then certainly things will be serious enough for an investigation.
I will start a thread to collate the relevant posts and if anyone sees any Trolling from the member 'pankkake' after today can you please quote them on the thread which I will link to here:
