I did this too but reddit reverted everything back to how it was and undeleted my account

Version control mother fucker, do you speak it?

But, in all seriousness: That is what they use for the comments. It is why a lot of the mass delete tools were “accidentally” undone during The Exodus. Because it was literally just rolling back. Theoretically there might be a limited number of revisions available but if you believe that I have a bridge to sell you. Because imagine if A Brown Person wrote a message then edited it five times so that Chloe couldn’t alert Jack Bauer to who to torture

I edited everything before deleting it, double-checked it was still deleted periodically, and it all got restored sometime earlier this year.
