My main gripe with RP, especially on a server that is now getting flooded with it, is people doing it in public channels. RP in your own homes, RP in LS's or FC chat or parties, but don't do it in /say in public areas filled with people. Like, I don't want to have my chatlog filled with your bad fanfic dialog while I'm trying to go about my business in town. I blacklist anyone one who uses /say for RP purposes around me, because it is unbelievably rude and obnoxious, even moreso than the RMT spambots.

You wouldn't walk down a busy street shouting some random story right in the ears of everyone around you in real life, and you shouldn't do it the game either.
