Just checked out the website. Looks like it just came into being o/a Sep 2016 around the same time Antifa started flexing its muscle. Typical white power meme with all the usual narratives. Never heard of this group before now. The whole site may be a false flag or the campus sign may be and attributed back to this group to spread the flames.
Smells like a hoax to me.
whois has an inception date of 2017-02-24. Where do you get 2016-09?
