In the post you made about "the most unsettling things people have found on the internet" you posted a story about someone who found a link on reddit that showed people a map thing with clickable webcams. I did some research (literally just a google search) and found a link to the service. It's been shut down. Apparently, it was a thing done by 4chan to display a flaw in TrendNet security. Since then TrendNet updated, but some cameras still hadn't updated their firmware.
Oh thank god. My friend actually taped a piece of paper over her laptop webcam camera because there were all these rumors about people hacking into others webcams and seeing what they were doing.
