You shouldn't post a tatoo in these pics becasue it identifys you if the cops catch you...
I did more thinking on this post and thought I should bring up, since that is my subject of expertise, that if the cops found me on this website as a point of interest in their investigation.. I'd already be a goner. I could sign up with a fake name and post google'd pics till the end of days but if a law enforcement agency of any level wanted to find me based on my activity on this forum they wouldn't need any of my personal information, any of the information I posted here, or any of the pictures I uploaded. I'm a computer programmer specializing in security, database cross communication, and web based user interfaces (security for websites people interact with, such as this one.) If they found me here and wanted to find me irl. It would take about 20 minutes to get everything they needed even if I didn't leave a pretty trail of breadcrumbs. And, also you should note, with or without the trail of identifying information left by me or not left by me... their method for tracking down my true identify would be the same regardless of what information they already had. You truly do leave a digital fingerprint. And, unless you've got your super magic computer cracking skillz to rep yourself wit (hehe) you aren't going to shade yourself well enough to hide from anyone. Hell, including me. It would take me a bit longer than 20 minutes... but not much longer
