To your concerns about people being picky Ic and not wanting others to join into their public scene, I'd say your best response is to leave them alone and not interact--as a person who holds those views will likely be a very rude RP'er. In my opinion, the adherence of IC stands above OOC communication, and not breaking that immersion is something I take somewhat seriously. You are right, there are /many/ people who will change their behavior based on what you communicate with them, because a majority of more criminal RP'ers want to get away with what they do wrong, so my best advice is as I stated above--keep as much as you can Ic and just play it out as it would progress should the world be reality. If they speak in public, they can be heard in public, if they do crimes in public, they can be held accountable by witnesses, and if they rely on OOC boundaries to protect their IC actions--they're a rude RP'er, and I'd find others to interact with at that point.
