Here are some:
Barging into a room with no +check and immediately notifying the room and scene in progress that you enter in sneak mode with a gun in hand and no one can see you, despite the room preventing this from being at all reasonable, despite no check being made , despite that player lacking the stealth skill.
Paging players and telling them that you've destroyed their building by collapsing the roof (With no storyteller involvement and no RP) and asking that they put in a request to staff to make this a reality.
OOCly berating players who attack you for perfectly good IC reason, then continuing to OOCly page and bother them even after they ask you to stop.
Generally demanding to do things that require a storyteller or, at least, a players agreement. Being an unreasonable tool when people disagree with your outlandish demands.
If you are going to do stuff like this, please page a storyteller first or atleast get a player consensus. You are not a staffer and you do not get to decide things like this on your own. /vent off.
