Poloniex did and they didn't confirm.
I do not believe that Poloniex had a qualified reviewer determine that the code was not improperly copied.
This part of the story is not over, because VNL is clearly guilty of misconduct when it comes to stealing code, violating copyrights, and misrepresenting it.
So you are implying that Poloniex, a trusted and high volume alt exchange, lowered Vanillacoin's needed deposit confirmation to 1 (only coin besides Bitcoin to have that) without doing a security audit and review?
Are you seriously this delusional? Peercoin needs 6 confirmations, Bitcoin needs 1. How much does XMR need? Not talking about your Bytecoin clone AEON here, because that will never get there.
