> But I think it would be impractical to restore to the correct version at scale unless they want to manually review to find the “right” version to restore.

They could restore all comments a month after controversy/blackout events from about a month before such events.

That would probably restore the majority as most people are deleting/overwriting their comments as a reaction to or as a part of these events.

Of course they could, but it’s very unlikely. Even if 10% of the users did this, there would be an uproar.

It’s much more likely they just disallow editing and deleting.

I was thinking more restore for their own dataset they might want to use to sell or whatever, I agree they wouldn't restore them publicly.
