May Be a good Idea to put a role play policy on your front page. To say to those interested whether or not you do it.. if you were the kind of person who did it would A to tell those who are friendly and want to help you get a little escapism how you feel about it along with what you would be interested in doing and B To tell the potential weirdos who want to draw you into situations you would be uncomfortable with to take a hike. if you don't at least it is a polite declanation and both would move on. Just saying.
