Sure, but it's also very likely that reddit is still retaining all posts even "deleted" ones in their database. I can go look at the profiles of people who haven't used their accounts in 12 years. I can use Arctic Shift to view posts and comments that users have deleted themselves... even from deleted accounts! All the data is still there. That's why a few years ago when people were deleting accounts it was widely suggested to edit every comment into gibberish before deletion, so the final edit in the database would be worthless. I remember when there were extension tools to do it like NukeReddit that changed everything to gibberish and then deleted it for you all automatically. Those tools had stopped working by the time the exodus due to the API changes happened.
Anyway, I wouldn't past that fucking pile of shit Steve Huffman to just be passing it off to Palantir because he's such a little bitch.
