It's no secret that technology plays an important role in our lives. Almost every single aspect of our life is ruled by technology, from smart phones to computers and the internet. That's why it's not surprising to know that Google and Facebook are keeping tabs on gun owners' firearms.
According to The Firearms Blog (TFB), the two tech giants are scanning users' pictures to look for serial numbers. They're then creating an index of every person's firearms based on the image scans. If you've posted a picture of your firearm on a social networking site and didn't smear out the serial number, chances are it's indexed on Google images. Simply type in the serial number in quotes and search images. What comes up?
The guys at TFB went through their image library and found images of various firearms and silencers where the serial number is clearly visible. They then typed it into Google and viola! Every image from their website showed up in the image results.
