I sent a creepy PM to a woman on the board once. It did not go well.
This was about five years ago. She was a popular member of the board who wasn’t shy about the fact that she was an attractive female, posting pictures of herself and stories about her personal life. She predictably got the occasional stalker type, so she was usually pretty careful about posting anything that would reveal truly identifying information.
She posted an OP one day about something that happened right outside her home. She referenced a couple of street names.
“Uh oh,” I thought. I fiddled around on the internet for about 30 seconds, and sure enough, it was enough to identify her home, and even narrow down her bedroom window to only three or four possibilities.
So I sent her a PM and she responded (I don’t have all of the messages any more, but I think it went something like this)…
Me: “You should really be more careful. The thread you just posted revealed enough for people to figure out where you live. You might want to ask a mod to take it down.”
She: “What are you talking about. No it doesn’t.”
Me: “Yes it does. Just going by your OP, I can tell that you live at XYZ intersection and here’s a link to a google streetview of what’s probably your window.”
She: “Ha ha. That’s not my window, but it’s close.”
I didn’t respond, and the next day, she went back to the thread and said that SOMEONE was sending her creepy stalker PMs saying he knew where she lived, and she was sick of it and was ready to quit the SDMB. Everyone sympathized with her and threatened to lynch the creep who PM’ed her. She disappeared from the board soon thereafter.
I still regret it and wish there had been a way to handle it better. Perhaps by keeping my nose out of it in the first place.
