As far as i know, there used to be a rule against that that was applied to people praising luigi, but not to people who said to kill all billionaires. I think it got removed or replaced now since i couldnt find it.
It wasn’t a rule, there was just ambiguity on whether talking about jury nullification for Luigi’s trial fell under advocating for violence, which led to some confusion (they later clarified that talking about it in terms of encouraging future crimes still counts as advocating for violence, but if the crime already happened or if it’s non-specific it’s all good, afaik).
