I think Rimu has tied this warning to the peoplesdispatch.org domain. I think this is a custom thing he did to his instance, because I didn’t find it in the PieFed codebase.

I don’t think People’s Dispatch is even Marxist-Leninist. I think it’s an international anti-imperialist media site. But I wouldn’t assume Rimu could explain the difference or care that there is one. Maybe all anti-imperialists are tankies to him.
