What's the worst experience you've had online?

Someone DM'd me my home address on a pseudonymous account I thought had no ties to my IRL identity.
- Probably someone who already knew your address IRL, but then found your online account and decided to mess with you.
  Siblings? Friends? Neighbors?
  I doubt someone who never met you IRL could've found you address (unless you leaked it somehow).
  
  How very post 2001 / Windows XP SP2 of you.
- For a while, while I was on reddit I had a new account send me "my home address" every couple weeks, I think it was the same person using multiple accounts. They always got the address wildly wrong though. Which is weird because it would have been very easy to figure out what city I'm from at least.

When I was young I had the bright idea to take a copyrighted, published book and only change the names of the characters to an anime I liked and post it up on fanfiction.net. Totally knew what plagiarism was then. Didn't think I'd get caught.
No idea why I thought that, either... People who like reading books also like reading fanfiction. Up until then I'd had a small following, so it was traumatic when all those people immediately - and very rightly so - got mad at me. My whole ffn account got wiped clean.
However, that was back when doxxing wasn't really a big thing and everyone was satisfied with my account being wiped. No one tried to hunt me down or call my school or whatever. I just sulked around the house a lot and then made a new account with only my original fanfiction writing. I can't imagine what it'd be like trying to do that today, even if I was young like I was back then.

When i was around 13-15 years old, i followed a creepypasta page on facebook, and since fb at the time was adding more automated moderation they decided to create a private group (so they didn't have to worry about ppl reporting their content) which i decided to join.
It was normal at first, people posted the same content there as the regular page, but then they started posting gore, and then cp, like actual, real cp. I also noticed that a lot of the members of the group had variations of the same profile pic: a heart with a smaller heart inside it.
I decided to gtfo of there, and a few days later i saw a report in the news about a symbol that pedophiles were using to identify themselves online: a heart with a smaller heart inside it.
To this day it gives me chills to think how in danger i could've been.

I once mentioned being proud of my mixed-race family and was called a racist.
Also, the day I decided maybe social activism wasn't for me.
- Ah, the horseshoe theory proving nutjobs who wants apartheid because they think races can't mix because checks notes they think there will always be a problematic power imbalance so lets not even try integration
  
  It is so weird that people would rather see kids orphaned than raised by a white family, but it was an important lesson for me.

Someone doxxed me and spread a photo of my face with the text "she said she was 18" superimposed on it (in meme format), and then spreading it in the community.
All because they took issue with a friendship I had with another user who "sounded young". Which culminated in the community leadership getting her to prove she was, in fact, not underage, "just in case" we ended up in a relationship because they "know how these things go" or something.

Had a previously banned user from a discord I moderate join back months later with my wife’s name as their username and a photo of her as the pfp

I never get too invested in any online community, but during covid, I made a discord for some irl friends. We all knew each other irl and understood each other's sarcasm, but one of them invited someone I had never met and took great offense at any criticism of Biden I would post in the political containment channel. If I posted a critical article or unedited clip, he would start calling me an immature Brunnie Bro. Absolute toxic Facebook brainrot shit. I shortly after made a alt account with a mostly same username, passed admin privileges to that and left. Most of the people on there still are so boomer that I don't think any of them realize that the person in their friends list and the admin account are different.

I developed this large world in Neverwinter Nights. I found someone to collaborate with and he stole it and pretended he had made it and put it online. He told me his reason was because he could.
- For anybody else considering sharing stuff you're working on in private, you can use tools like freetsa for verifiable timestamping before you share anything to prove you had it first. Timestamp multiple versions with your name on it as you progress.
  Others who you share the files with later will not be able to come up with provable timestamps older than yours

  Neat!
- Psychopathic behavior right there
- Who was it?
  
  One of two brothers who ran a server called the nameless realm.

all of them were on reddit; they lol'ed and shitposted about various genocides and institutional tortures and it made me leave.
- oh, ew

I literally just posted about this earlier today. I used to frequent the Something Awful forums. I know, I know, but I was young and at least it wasn't 4chan.
About 14 years back, I was having big issues with my partner and wasn't sure what to do, so I asked the forums for relationship advice. I actually got a fair amount of well meaning advice, but also a harasser. They initially just ripped into me in response to my request, but SA was full of trolls so I ignored them. Then they responded to another new comment I made awhile later, but the forums weren't huge. Just a coincidence, right? I continued to ignore them.
We went camping and got back a few days later. I checked my SA account and found this person had gone through my post history mocking and bullying me and had collected info to try to dox me. I was pretty carefree with what information I disclosed back then and they had a lot. They knew or at least accurately inferred: the name of the small town I lived in, the areas of town we had lived in, the year/make/model of the unusual car my now-ex drove, which university I attended and my major, where I worked and more. This all freaked me out so I reported them.
The mods' response to my reporting a user for harassing and doxxing me was, and I quote, "LOL faggot". Such fond memories. I quit using SA immediately and worried for weeks that something awful would happen. Pun intended. Luckily nothing did. I have scarcely thought about SA since until someone brought it up here a few hours back.

Me: I have an idea to improve the experience of using an IVR (the system that allows callers to navigate a menu by pressing a number on their phone)
Reddit: die slur

SLURRRR obscenity why would anyone EVER want that??? IDIOT STUPID kys

Trumpers

Young adult, novice queer. Made a post on Tumblr about how I was tired of both gay users bashing ace people, but also ace users bashing gay people, and I was done with both communities. For context, Tumblr users in this era looooooved to dunk on posts about lesbian sex and I was sick of it.
Older mutual who's opinion I really cared about sent me a long DM about how I'm not ace anymore, and how "that's nice for you, but real people can't change their sexuality," before ripping into unrelated aspects of my character.
I've technically been treated worse especially as a child, but that one stands out because I liked him. :( And it made me paranoid about being queer "wrong" if people weren't allowed to change their label.
- How long ago was this? I'm so sorry about all that :(
  
  Thanks <3 it's OK, it has to be around a decade now. It just came to mind as the worst experience because in hindsight it was so stupid to torment me so much. "Oh no I offended the guy who thinks his sexual orientation is thinking gay people are gross 🥺"

I've had some really shitty experiences playing wow with random people.
- OK now I understand trigger warnings. To be honest, some of my best online memories are from WoW as well.
  
  Yeah I would agree with that also. But most of the good memories weren't with just random pug groups.

One time I was joining a meme group chat on Facebook Messenger and the admin told me I would be banned if I didn't send her pictures of my butthole. I accidentally posted those picutes to my main account later on and got my account permabanned.

Probably when someone advertised my discord server on 4chan

- How did you get permabanned from the steam forums? This reads like a tailgater blaming the person who did a brake check...
