My "operational security" is not what it should be.
I was buying a gun at a local store today and the sales man asked me if I got my hunt tags straightened out. I asked kind of a "huh/what?" and he said, "Your post on the hunting group in the facebook page." It's a closed group, but there are 4k members. All you have to do is google is my first and last name and you have everything you need to know in seconds. The first result is my place of employment. The second result will get you my address along with a satellite image of my home. The fourth result will get you my credit score, date of birth, income (significantly inaccurate), and religious preference. (As well as a link to that info for every one of my neighbors.)
So anyone who sees my name in an online hunting group or forum would assume I own at least one gun and would know exactly where to go to get it and when I was most likely to not be at home, based on my place of employment. It is well known at my school by both coworkers and students that I own guns, shoot competitively, and hunt. Essentially, I'm a sitting duck waiting to be plucked.
