Right..that was my point. I know that when I type anything it is public domain. I hardly think a VIN number is of any consequence to anybody, hell you can see modern ones through the window so all are available to be "Taken" As far as my name, there are 6 Robert LeBlanc's at my Bank branch. It would be difficult to tie me to any one place. BCA# just ties my nickname and info posted from this hobby to my name which is benign. At worst I will get some targeted advertising but I block those anyways. The things to never type out in public are, Home address, Phone numbers, any financial id numbers ect. Personally I think a membership number is of no use to any nefarious individuals.
