Persnickety,
I think your topic suggestion, and your intentions, were perfectly fine.
There are just things people aren't aware of, because people in general don't pay any attention to their own security.
People often make lots of public comments and posts, where they never really say more than little tidbits about themselves. However, for many people, if you were to read read ALL OF THEIR POSTS, you could probably figure out where they live, what day of the week they go grocery shopping, and even what to feed their dog so it will let you past it and into the backdoor, lol.
The topic you posted is perfectly fine.
I'm just reminding people this is a public board, and that they should be thoughtful about what they post publicly, as a general rule.
