I have seen posts from Soleil at DU, and she's actually one I thought responded with good answers to whatever some of the idiots said over there. She was pretty open when she first came onboard about the topics she recently posted, and it didn't take much to figure out who she was. She also announced that she left DU, and I happened to see that thread in the DU lounge.
It seems conceivable to me that certain people at DU only visit safe topics, look for likeminded people, and learn early on to ignore threads with people who they don't agree with. I bet there are CC members who never read the dumpster section, just as there are sections on this board that I've never been to before.
Soleil, I'm relatively new here on CC, but from what I know of the members, no one here would stalk you on FB.
