What is the scariest thing you’ve come across on the internet?

When I was about 15 years old I was on PornHub and then this popup appeared saying I have been caught watching CP and that my local police station will be contacted with my details unless I send them money. Scared the fuck out of me, switched my computer off from the power point, took a breather then proceeded to format my hard drive and install a fresh copy of Windows.

Another time I stumbled upon a forum where the main topic of discussion was animal torture. These scumbags went into extremely graphic detail about what they did to cats. It didn't really scare me but I was pissed off for a few days because there was nothing I could do to stop these pieces of shit.
