Slender

The Slender Man stabbing, where two girls attempted to stab their friend to death in order to please a viral fictional character. The creepiest part is watching the police interviews of the two girls, just a couple hours after the stabbing.

Missiles

One I can still remember is that false missile/attack alert that went out in Hawaii. People rightly freaked out thinking the islands were getting attacked until it was all sorted as a false alarm. I can't imagine how much that probably messed people up, even if it was only for a short time.

True Sadism

"Couple Drowns In Front Of Camera"
A youtube video showing a newly wed couple accidentally drowning in a pond in Yemen, Caught on camera. Discovered later by a passerby. Just uploaded to youtube on 2013.
Thinking about it still distresses me a little bit. How it happened so suddenly and how someone could just upload it to youtube like it was any other video.

Not Safe

Snowden's exposure of NSA's and CIA's control of information we thought was private. Though probably not the the first person, certainly most popular.

The End Of The Road

McKamey manor is on YouTube and somehow allowed so I'd say it counts. It's also odd that it's all over the internet and it hasn't been shut down. Someone almost died after being dragged through gravel behind a truck with nothing to protect his skin. The goal is to scare you out of winning the prize. No one has won because they will kill you to prove they don't lose.

Monsters

A Norwegian hacker uncovering that the largest child sexual abuse website on the dark web was being run by Australian police in order to bait and then arrest pedophiles. The forum had over one million registered users who made accounts, and was one of many like it. They made an amazing podcast about it called "Hunting Warhead". I have listened to and read a huge amount of disturbing content and I almost threw up even though there is almost nothing graphic or violent.

Deep Dark Web

The Silk Road. There was so much crazy stuff going on there, feds were moving in, Ulbricht was hiring hits, scams for thousands of dollars were being run just before the site went down. I mean Jesus even the founder was scammed out of his money. Those chat logs between Ulbricht and the people he was hiring/"killing"...chilling.

Your Device Listens To You

I would say the emergence in stories about receiving ads that are related to conversations you've had. For example, I got called into the counselor once and we talked about therapy options, then a few hours later I opened Instagram and got an ad for online therapy sessions. I've had this happen several times but this was the most memorable because it was right after I had heard about this occurrence but I didn't believe it. By now I'm sure most people wouldn't be surprised that this happens but still creepy to think about.

Massive Political Complications

The ISIS execution videos online, and even scarier the fact that they learned all that from the execution videos of Mexican cartels, especially the "Zetas" witch are still active a drive away from Texas.

BTW, the Zetas got trained by the US government, they where part of an elite group of the Mexican military, trained alongside US elites, and one day they all departed at once, taking with them lots of heavy weapons and starting a cartel.
