It's a neo-nazi/white nationalist forum. It's still active I believe behind Tor, but not nearly as accessible, far fewer people actually participating. We're in an era where young men radicalize each other on message boards like these until one of the truly unhinged members heads to a synagogue to murder people worshiping. As we've seen so many times in the past year, they'll often post before they do it, leaving behind a manifesto and a crowd egging them on to get a "high score."
I wish this was actually an outlier and not very common, but unfortunately if you monitor these forums you'll see men working up the courage to commit a mass murder of their own every single day.
In my opinion we should try to put as many barriers we can in front of these types of communities, and it sucks that cloudflare is still working with some of them.
