After 13 years, I had quit reddit 1st June 2023. At the time I joined beehaw (lemmy.world didn’t exist) and used the redact utility to delete all my posts/comments (we could at the time delete instead of mass editing.
I lurk sometimes some niche communities or go on reddit from google search, I never comment or upvote. I sometimes click on my user to see there was no comments/saved/etc.
Yesterday, randomly, I clicked on my username and saw all my 2023 and less post, 13 years of comments, I was like WTF, after 2 years, reddit decided to take an old backup or something and undelete all my comments!!!
As now redact only do mass editing and pretty slowly, I used something else, https://github.com/Jelly-Pudding/ereddicator/tree/main, followed instructions, it deleted ~3600 comments in less than 2 hours.
I’ll monitor from time to time if reddit keep undeleting them, to feed their AI…
Reddit has had a “bug” for years where when you delete comments and posts it says they’re deleted but never actually verified they were.
When you delete quickly the API just says it’s deleted. You have to reload and purge multiple times to actually remove your content.
I wouldn’t put it past Reddit to undelete content, but at the time a lot of the complaints Reddit was restoring content were due to this bug.
It’s been a bug for at least 10 years.
