Links are not the only way to cross the line. Plaintext of the URL is also forbidden.
"8chan" should be okay, but I am not sure it is. I think it should be okay becuase "8chan" even with .net or .com added is not the URL to the forbidden website.
I also suspect that a one-step removed indirect link is grounds for post removal. xample - link to a twitter post where the twitter post links to eight-chan is "too close for comfort" for some FR mods.
I was just going to post a link to a tweet that had the cha n WORD in it - now I’m gun shy.

The day a twitter mob can change a headline on the New York Times this paper is truly finished and replaced by a new kind of 1984 Ministry of Truth. The news is now what people say it is.
