I know of a young man who was outed because of his myspace page, nothing "apostate" just other religious says was posted on his site. The elders swooped down on him and right now his fate has not yet been decided, but it doesn't look good.
Also, remember that not everyone who PM's you is at the same place in recovery as you are. If you have a lot to lose and you are not ready to take that final step, be careful of what you say in PM's especially if it is a new poster and you have no history on his/her beliefs.
