I have nothing to prove but if you will notice that rpietila did in fact respond in this thread and did not dispute anything I posted. (or smooth for that matter)
I don't dispute anything BitcoinEXpress said. I can't confirm the existence of the claimed exploits but I can't prove that they don't exist either. The stuff he said about trolls being annoying and not being affiliated with the core team in any way (rpietilla isn't either BTW, he is just a vocal supporter) is absolutely true.
