You are right. Rats always snitch on each other and all of these dirty players are classic rats, hiding behind their numerous false accounts on here.
Popescu's best buddy the Frenchman pankkake is also in this deep. He has taken money from MP to carryout attacks on all things not MPEx. Pankkake knows enough to put MP behind bars for blackmail, extortion, commercial attacks. If the FBI put pressure on pankkake he will talk. The French bow to pressure very easily. Always have.
For his commercial attacks alone Popescu could be fined up to 30% of his annual turnover/sales under EU law. That alone would bankrupt him and his business. He can also face prison (in some EU states) for infringing EU competition laws.
