Well, if it's in the interest of advancing the RP, then it's totally fine - but, otherwise, you're just being a dick.

Oh, I didn't mean the story-telling aspect of it/generating events. I've seen mods make characters that didn't conform to the standards they'd set for no real reason other than they wanted it for personal use, and also roleplay scenarios that they'd specifically banned. For an example, I remember running across a site once where they'd banned mature sexual content, except the owner decided to break that rule in the public forum anyway... it was rather bizarre.
