The Fascist Republic of Warsaw has been banned for violating NS and community rules, specifically for intentionally seeking to upset the other players (trolling).
Fascist Israel has been banned for violating NS and community rules by using an explicitly fascist nation name and Techno Vaishnavism has been banned for trolling and incredibly confrontational and inappropriate posts.
Future Beans has been banned for election misinformation. NS is rather inconsistent with its guidelines, though I would note it has a clear misinformation policy with regards to Covid-19. Furthermore, while not explicit or clear trolling, election misinformation can be weaponized in such a way. I considered simply labeling this trolling, but I wanted to be clear that I felt the thing on its face was significantly harmful enough that it could stand on its own.
