I remember a server where swearing was banned entirely, the reason being "I have never met a good person who can't hold their tongue."
There was also a few times I played barbaring's jailbreak to see if he took his criticism, but he kept his awful admins after removing them for 10 minutes (even though they would constantly abuse their powers) and would not remove the admin only armoury that had powerful weapons and a shield of all things (which was designed in a way that an admin could let anyone in but more often than not they wouldn't)
He also kept using blockality despite it being not good for most uses, including this server.
