On another board long ago I got into increasingly explicit flirting that ended up going offline into e-mails before I realized that it had gone further than I wanted it to. I am married and felt bad for doing it. (call me old-fashioned) I disengaged from the interaction with the woman. I never expressly identified myself to her but I think I gave enough clues that she probably figured it out.
About that time she, being a very skilled seductress, got an unattached guy interested enough that he supposedly flew to see her, got serious, etc., but eventually broke it off. From the comments I saw she apparently had some severe mood swings and probably some other issues.
I thereafter saw her post numerous times on a board, increasingly "out there" until she abruptly stopped posting about a year and a half ago.
As strange as it sounds I have wondered if she is okay since then, given her problems. Although she told me her name (supposedly) I don't want to chance it by actually trying to get in touch with her to find out. I got this weird vibe that she was unstable. There are some problems we don't need.
My rules I learned for posting:
1. Don't agree to allow PMs or e-mails. You then can't be pressured. Keep it all public.
2. Don't post your location. Don't use even your first name, or other identifying information such as where you grew up, what you do for a living or anything else someone can use to stalk you. Your IP address will identify the area but only the forum administrator will know it. Real photos? Forget it. You are asking for trouble. Your photos can be pasted into any other context. This applies to all forums, not just sex forums.
3. Don't use the same username on a sex board that you use elsewhere. Remember that one piece of info from an innocuous board can be combined with other info from another board to track you down.
4. Anything and everything you read can be true, false, a lie, a fantasy, a confession, the friendly banter of a sweetie, or the deranged rambling of a serial killer who is munching on their most recent victim while chatting with you. Don't assume anything, especially that you have figured out who and what they are.
5. What you post on the internet may last forever. Do you want your mama or daughter to see it and know it is yours?
