While I understand you take precautions, why even bother posting pictures of your bike? For the little attention you're getting, you've voluntarily linked that particular bike in the picture, with your name. It doesn't take much social engineering to befriend you, or to find out where you work, live, ride, eat - if you're socialable on here, you've probably already disclosed quite a bit about your habits, or lifestyle. Best be safe, and don't make many friends on here, don't go on group rides, don't disclose anything that might make it easier to find you, or where you ride. Right? Of course, to each their own. It's your life, and it's your bike. It's also you bears the consequences of all that you do.
