Just collate them based on edit/deletion date… Each post will have a last-edited attribute that can be used for sorting. Even more so once the AI is bootstrapped enough to start recognizing the standard protest edit messages. At that point you hardly even need human oversight anymore, because the bot will be able to recognize “that’s a fuck spez edit, ignore that; this post looks good; that’s a Shreddit/PowerDelete edit, ignore that” and so on. Can even have it fetch the previous edit automatically when it comes across something like that, to a point where a comment removed by a PowerDelete tool is nothing more than a cover letter that states “there was once a real human-generated comment in this location”.
