Wikipedia was launched in 2001 and has been growing at different rates ever since. As of October 2025, its English version has over 7,080,000 articles. However, not all of them are safe for work.
Last week, Reddit user Herequeerandgreat asked people to share the most disturbing entries they’ve stumbled upon in the online encyclopedia. Whether it’s due to the Halloween season or some internal human morbid curiosity, the discussion has caught on.
We went through thousands of comments and hand-picked the controversial ones, on the off-chance you're looking for a topic for your next rabbit-hole deep dive. Proceed at your own risk.

"War Crimes" in general. Then "Japanese War Crimes".

I like to think that I have a pretty strong stomach. I have a morbid curiosity. I enjoy horror and true crime..and I've seen more gore/shock images than I ever should have, but the descriptions and photos of what happened there made me physically ill when I first encountered them.

The fact that Japan as a whole has never really had to recognize or reckon with what happened there and in other places makes me really upset. Yes, the bombs dropped on Hiroshima and Nagasaki were horrific war crimes in themselves...but they don't erase Japan's guilt. You can be both a victim AND a perpetrator.

Sandy Hook Elementary.

Reflxing:

Still can’t believe that happened and how it caused absolutely no change. 6 year olds are so little.

"Unit 731." I thought I’d seen dark stuff before, but that one genuinely made me close my laptop and go for a walk.

But as Wikipedia's database is growing, so is people's skepticism toward online resources. Earlier this year, a survey of 2,000 U.S. adults found that only 41% of them believe the content they consume online is accurate, fact-based, and created by a real human.

Another 78% agree that the internet has "never been worse" when it comes to differentiating between what's real and what's artificial.

Social media posts (48%), news articles (34%), and chatbots (32%) are the top three most suspected sources when it comes to AI-generated or misleading content.

I can’t stand The Nutty Putty Cave and the story. Horrible and devestating tale. Just reading the story makes me claustrophobic.

Josef Friztl is up there.

ManMan36:

I remembered hearing that name somewhere and decided to look it up. I wish I didn't. Good god he might be one of the most evil people alive.

How the hell didn't the wife find out what was going on in the basement in 24 years, not a week but 24 whole years.

War crimes in the Russo-Ukrainian war.
The fact that this kind of barbarism exists in modern societies while russians openly threaten to cross european borders after Ukraine falls.

Those polled believe that 50% of the news stories and articles they come across online have some element of AI, whether it be images or the actual written content.

But perhaps the most concerning part of the results was that less than a third (31%) of respondents are confident in their ability to differentiate whether, for example, a product or service review was written by an AI or an actual human being.

Little bit of a different flavour from the rest of these:

Timeline of the Far Future

I defy you to read through the whole thing for the first time and not end up disturbed.

vampire-mom:

I actually find this stuff really comforting. I spend so much time worrying about the damage we are doing to the earth that the knowledge that someday human beings will be extinct and the earth will heal and give rise to new species and the cycle will begin a new really settles something in me. even knowing the earth itself will die and its atoms will join the fabric of the universe in a new way and then the universe itself will die before another big bang happens and we get to do it all over again just feels right to me.

List of youngest mothers. No longer exists on wiki. Makes sense since you couldn’t protect the names of the children.

Minute-Phrase3043:

I remember this. Stumbled upon this as a teenager. I was horrified to see the list. And that was when I didn't know as much about the damage pregnancy would cause them. I never want to look at that list again.

The history of notable Defenestrations is oddly as entertaining as it is disturbing….

Russia is a stark example of how even states can exploit online information systems to manipulate public perception. Researchers have documented how Russian operatives used a network of automated sites, known as the Pravda network, to flood the internet with propaganda targeting Western audiences beyond the war in Ukraine.

The operation extended to Wikipedia as well. Russia's human contractors edit articles to include links to Pravda network sites, exploiting the platform's credibility and the fact that many AI systems give special weight to Wikipedia content. Because Wikipedia serves as a trusted source for AI training data, these manipulations allowed false narratives to spread further and faster, affecting the answers that chatbots provided to users on topics such as the Ukraine conflict. (Experts warn that this approach is highly scalable and inexpensive compared with traditional influence operations. The same methods could be used by other actors—from political operatives to commercial competitors—to skew AI outputs in their favor.)

So the bottom line is that, even though it's fun to click around Wikipedia and fall down rabbit holes, at the end of the day, each of us is responsible for verifying the information we consume.

Cyclopia. It's a birth defect in which the brain fails to divide into two hemispheres. It's incompatible with life, as babies with Cyclopia are either stillborn or [pass away] shortly after birth. As the name implies, these babies have only one eye, and some of them don't even have a nose.

I believe the David Parker Ray.

Wikipedia page used to contain the audio file for his tape he would play to his victims. I know for certain there are snippits of the transcript still on there and just reading his words are absolutely disgusting.

I also had a year long phase when I was like 16 where I was really interested in historical fires and human crushes. But those are stories that have made me more aware of my surroundings, I am much more cautious in crowds, and it's also very interesting to see how tragedies force safety innovation. For example, the Victoria Hall crush in 1883 lead to the invention of push bars on doors.

There may be far worse, I don't dive into wiki like I used to but Peter Scully's is one of the worst I've read. 


Edit: Apologies to anyone who has already read it and a little shook or upset. But a PSA moving forward there is quite a lot of triggering things in this so read at your own discretion.

When I read about his crimes, I truly almost vomited. I was in a dark daze for a while.

Ian Watkins (Massive trigger warning for CSA).

jarred_pard:

Ian Watkin‘s wiki is bad but tame compared to the actual court transcripts (do not read unless you want to be seriously disturbed and a little [messed up] from the experience)
