I've always said I could put together a real good personal scam on someone if I was a crook. Just research their posts, find out about their family, dogs, vehicles, likes and dislikes, beliefs, etc. Then work up a story where it sounds like you know them, or they should remember you, or you knew their departed parent, etc. All the info is here for the taking for people who post quite a bit on the internet.
I do believe if a person worked at it, they could come up with my name, address, phone number, etc. Not from RV.net, but by getting bits and pieces from here and there.
While it would be nice to know everyone's name, I don't think it's necessary for a forum.
