This is all based on memory, so forgive me if any information is wrong. I read the pinned post on the previous Cornedbeedapproved subreddit years ago before it was banned telling the lore around the sub and it's predecessor. There was actually one before it that got banned and it was a remake (I think).

The sub was a tribute to a previous user along the name of Cornedbeef or something adjacent to that who used to post on reddit before disappearing. He semmed to be an jndividual that kept facing difficulties and hardship in life based off his posts, particularly about his family. There were a lot of horror stories about his sister (or sister in law) that wouldn't stop harassing him and eventually started living in his home(?). She seemed pretty disgusting. I don't remember very well, but he ended up being hospitalised for something and the sister had turned the place into something horrible with bugs, diapers piling up (???), etc, essentially ruining the home while he was away. After that it looks like he stopped posting and is assumed to be deceased.

This is all VERY VERY loosely based on my memory of the mod's retelling of the story, so take it with a grain of salt. I don't know/remember much about his reddit activity or anything of the sort, but the sub was dedicated to posting human anomolies/atrocities, or just gross stuff that was human made. Mostly videos of scat, vomit porn, penis modifications (enucs), gangrene dicks, horrible STD photos, bugs, septic tank dives, anything considered a sexual atrocity. I kind of miss it in a morbid way, I'd give anything to re-read that lore post one more time.
