I want to laugh a little but not sure if you're joking or serious. In case you're not joking around, I will try to briefly say that I thought there was a way to read previous versions to posts and comments on Hive.
Long story short, I think that is not true. Well, I don't know exactly. I would have to go look around and investigate it more to determine what might be possible.
But last time I checked earlier in 2021 I think, you can do it on Facebook, you can look at previous versions to posts and comments. I know Facebook is not a blockchain. Maybe I confused Hive with Facebook.
