It seems the author got all his/her ideas from NXT thread of https://bitcointalk.org/index.php?topic=397183.1140 and took the issues without context. NXT community has discussed almost all the issues in quite details in that thread.
Yeah, I would just ignore that idiot, he offers a paid service for crypto advice, he's obviously a miner and not worth our time to discuss.
Some people with twitter should respond to the tweet and how Hazard feels regarding NXT. The guy calls many coins "SCAMS" from what I remember (go look in the original BTC NXT posting lol). But anything negative needs to be corrected with good evidence against the negative.
