So I just became aware of this last week, I'm not all that internet tech savvy. Just thought I'd let others know. If you post a self pic on this site or any other site, and say you have the same pic on your Facebook or whatever, Google Image (other search tools too I'm sure), can match that pic posted on here to your profile, compromising your identity. Regardless if your face is cropped or whatever. So keep your social media profiles set to private.

Internet sleuths on reddit have been doing this to identify anonymous posters or identify people, that's how I heard of it. Something to think about.
