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.
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.
