I hope you will see the evidence and retract this post so as not to spread further FUD. Thank you.

Why would/should he do that? Disputing criticism is always better than ignoring it. Of course if someone is just spamming insults it is OK to flag or want it to be retracted, but as long as there are civil arguments being made I think they need to be answered, which I think you did with this comment. I don't understand the nitty gritty of the blockchain, but I dont think talking about potential flaws is FUD.
