Rimu basically went nuts and made a List, like The List from the Tesseract guy. Except this one was baked at the code level of the software running the backend of the communities, so communities got forced to ban left-wing aligned content on update without a choice in the matter. Plus, the software had CCP-style shadow profiling of people to hide their posts, and in at least one known case editorializing someone’s posts on client view, without the poster being made aware that their content was being editorialized (essentially, attributing them false speech).
