I was playing on the creative server at 5pm AEST on Wednesday and a user by the name Guan_winters killed me with a potion even though I was in creative. He was demonstrating how to use it and if I wanted it. Supposedly many people have it and that an admin said it was ok but I just think that it would be a gamebreaking item to own.
I think potions only work on your plot or plots you're trusted on, so if they are trusted/added to your plot they can use it. It is a splash potion of instant health and the amplifier is so high it kills the player.
Whilst we don't currently explicitally have rules against the use of potions, we do have rules against deliberately annoyimg other users - which repeated use of a death potion without consent would come under, and so could be punishable depending on full details of the event. We also provide access to /god which should make you immune to death potions - if this command isn't helping then please let me know so I can try and find another fix.
Unfortunately it is very difficult to fully regulate items which players can obtain on a creative server, so unless something is being used to repeatedly cause issues to players, there is very little we are able to do.
