I wish i could, but this was 2 years ago, and once the post blew up huge, OP deleted it. Some Lemmy historian may have a copy, but alas, i do not.
Basically, OP posted a question where they said they didn’t want to poop during the upcoming weekend, and then asked how they could keep from pooping for three days. This was shortly after the Reddit API exodus.
The comments were very helpful, reasoned, and…Nah, im just kidding, they pretty much went the way you would expect, with lots of wild speculation about why OP didn’t want to poop for three days, and lots of “helpful” suggestions about how to not poop for three days.
Strangely though, i think the post did a lot of good, as it showed a lot of ex-redditors that Lemmy could work as a reddit replacement, and be just as goofy as the original.
Plus, it was a shared mythos. He created the main core of it, but others contributed as well. So, figuring out copyrights would be difficult, since some stories reference other stories. Remember, they thought they were just writing some horror stories, but that they would never be something anyone other than other horror story enthusiasts would see.
IP was not a thing yet, and they were just writing for fun. A modern version would be the shared SCP universe.
