I don't know anyone who really cares about the people who do *real* RP (as in, know IC vs OoC times, have done research and stuff like that. Are serious about it and all), its the people who do it to annoy others (macro every GCD with text, Ice Mages, and so on) that are the issue.

And ERPers doing their thing where others can be affected. /tell /party /linkshell, lock the house you're using, something to keep it private or don't do it.
