nubbins you may be asked or told to hand over this info by dotcoins lawyer, I would suggest you do that sooner rather than later.
Dotcoin is right, this is a scandal and is a breach of EU anti-competitive business laws and those carrying out this unfair competition will be seriously fined (up to 30% of their annual sales - potentially devastating for the company) by the courts or the EC for their law breaking. All the money Dotcoin pays out in legal fees for this case will be paid back to him in full and on top of that he can successfully claim compensation for damages and that will be paid by the actors in this case be they part of a company or acting as individuals.
We know 100% that if Romain Bignon is not pankkake himself that he knows him personally and has been to meets with him:

'pankkake (Da Pin Gouine)' - so pankkake is known as 'The Penguin'. And Roger Floupard owns a website about Penguins - www.engu.in
So we have the right people here, be it Romain or Roger, there is enough evidence to take this to the French Police or the EC.
