I'd only ever pull something like that to the OOC realm if it was a case of metagaming, or something where I strongly feel that something is being forced down on my character which would have required my OOC acceptance first because of how it affects the day-to-day RP, for example inventing a false secret to spread around for ill-intended purposes - but I stress that this would have to be of some magnitude before I would react on it.
