This is OT, but I did a stupid thing, try to be so careful. They had a little ad on youtube with a fun little test, then said they'd give you your pin # to get the results. It asked for cell #, just have a regular phone, so I entered that number which was really stupid.
I don't think anybody can do a reverse lookup because I've had it unlisted for years, but it looked like some singles site. I've got the phone off now, but am afraid someone is going to start pestering me, hope I don't have to change my number. Even if I had caller id, if calls came from a bunch of different numbers, I wouldn't know who they were especially since various ones I do business with on the web have multiple phone #'s. The area code could be an alert though, maybe.
I've run into something similar - so I gave them the local Dial-A-Prayer; I got in, and they got saved!! ;^)
