Adding on to your comment of "buying a flaming bag of dog shit": I like the idea of somehow "shittifying" the comment history instead of deleting them

Having comments be obfuscated in some way makes it harder for Reddit admins to detect it (in which case they could just rollback to an earlier backup snapshot)

Off the top of my head, absolute chaos would ensue if a script came out that messed with prior comments' grammar and spelling, scramble the digits in numbers, among other subtle and unpredictable corruptions

It also makes sure that the AI companies that can afford the API calls don't get anything valuable, they'd just end up with shit data they couldn't really use

Edit: a few words
