A few days ago I deleted all of my posts and comments from reddit, but today they somehow reappeared.
I don’t know if that’s a bug or the admins themselves are restoring content, but I’m sure they’d have incentives to do so considering that they make money from your content, whether that is from generated clicks to the website or from selling those data to other companies to train AI models.
Removing the name isn’t enough. Some posts might contain stuff like “my real name is … and i live in so-and-so city” or “my birthday is today too!” which would all count as PII. This would need to be scrubbed too.
For the “[deleted]” part - there’s another way that happens. If you delete your reddit account w/o deleting the comment/post, then your text stays, but “[deleted]” is reported as the user who wrote it.
