i went looking for old comments and posts i had made after i overwrote then wiped them. They're still gone. i looked again several months later, and they were still gone.
so, unless reddit did a massive restore of everyone's comments/posts except for my 4 accounts, then i don't believe they did it at all except for a select number of top contributors who deleted their content.
On the other side of the same coin: When I mass edited my comments before quitting Reddit, I got site-banned. Basically, my first account’s automated edit got me auto-banned from several subs with pro-spez mods. Some subs had set their automod to detect when people were using the more popular methods of auto-editing, and set the automod to ban for using them. Then when I did the same with my second (and third, and fourth, and fifth, etc…) account, it almost immediately got site-banned for ban evasion.
Basically, account 1 was banned from a sub, so when account 2 started doing the same thing on the same IP address, it was flagged as ban evasion. And ban evasion is one of the few things that will get you banned site-wide instead of just from a specific sub.
I went back and checked a few months ago, and all of those site bans were lifted and the edits were undone. Likely because a site ban prevents the comments from showing up (which hurts Reddit’s bottom line, because they show up as a bunch of [removed] comments instead,) but also prevented any of the edits from actually being published. So when they lifted the site ban (to get those old comments to show back up again) it was as if I had never edited them at all. I had probably a million karma spread across my various accounts. I was extremely active at one point, so Reddit had a direct incentive to unban those accounts with literal thousands of comments.
As I said in another comment, I was not suggesting that Reddit would restore your comments to public view.
there's no evidence to suggest that, either.
Except for incidents like This
There’s no evidence of the contrary either.
You are assuming edits overwrite existing content. Instead of overwriting, they could just store the edited post as a new entry in the database with a higher version number. Then, you only show the latest version of each post to the end users while keeping the older versions available die Reddit’s own use.
In fact, it is extremely likely they do this. It is basically a necessity if you want to be able to properly moderate a site like Reddit. Otherwise you could simply post spam or unsavory content, and then overwrite it with something benign an hour or so later, before there were enough reports and a moderator would have gotten a chance to review it.
i have seen no evidence to suggest otherwise, but thanks for sharing your theories
based on what evidence? your baseless speculation?
The fact that they managed to restore overwritten posts after people started to delete their history.
this could also be explained by sketchy scripts failing to completely delete posts/comments, which i even noticed myself when checking that they had done their jobs properly. as i mentioned in another comment, i had to run the shredder scripts several times for complete overwrite/deletion. or it could be database errors failing to register edits/deletions due to extremely heavy loads at the time. it could be a lot of things.
the point is that we don't have any direct evidence of what it actually was, just a lot of circumstantial evidence and a lot of speculation. nothing definitive.
Reddit used to be open source. There is still a copy of that source available on github. It’s 7 years old so it’s probably significantly different from what they are running now. Still, it gives some insight into the design.
For example, deleted comments aren’t deleted, it just sets a deleted flag. Example code that shows this.
I haven’t dug around the code enough to figure out how editing works, it’s Python code so an unreadable mess. The database design also seems very strange. It’s like they built a database system on top of a database.
FWIW even when you properly delete something from a database table, the deleted row can be reconstructed from the audit tables. And even if that weren't the case, databases are regularly backed up to tape drives or whatever - when people delete or munge all their comments, Reddit doesn't go back into all the backups and make the same changes there. In fact, I would imagine that when they sell their shit to companies for AI training, they sell old pre-AI backups rather than a latest copy.
This is not evidence that overwritten and deleted comments could be restored to the original state. Moreover, that points to the original source code of Reddit, not the current code of Reddit.
This is also not evidence that deleted or overwritten and deleted comments have been restored. This is merely evidence that, at one time, this is how deleted comments used to be handled.
All this is evidence of is, as you put it, things are very strange in the code.
I never claimed it was evidence of how it currently works, only that it gives some insight into how Reddit was designed. I would be very surprised if they changed this aspect of the design. It makes sense to not delete comments or edits for reasons I mentioned before. Unfortunately we won’t know for sure unless Reddit confirms it.
It seemed to happen to some people but I wouldn't be surprised it it was just some sort of coincidental database fuck-up
i suspect that was more likely incomplete deletions than reddit restoring content. those scripts were pretty janky. i had to run mine several times to get everything, as it didn't work fully the first couple of times. same with the overwrites. took a few times for those to get everything, especially on older accounts with lots of posts and comments.
I'd read some claims that posts appeared to be deleted but then later came back. Could've even been some sort of caching shenanigans with their local browser though I guess.
oh, right. i suppose that's possible. i've seen similar browser cache fuckery on other sites before.
as i said in a previous comment:
but there's no evidence they're keeping everyone's deleted-but-restored comments from public view or whatever it is you're suggesting. or even anything past whaat this one person found. in fact, there isn't even any evidence that what happened to this user was intentional and not a bug or some other fluke.
sure, reddit would have a vested interest in doing this, and what you've presented is suspicious, but it's hardly conclusive of anything. all it does is raise more questions. but it doesn't provide answers.
