I don't think the delete function actually deletes anything. At best sets a flag.
If i wrote public forum software, that's how I would do it and batch delete only comments that no one asked to undelete in at least a few months...

They usually store some history in a logging database that can be reverted at some point in time
Nothing is really truly hard deleted on the web most times
Might have changed in the past 2 years, but unlikely.
So the question would be, if Reddit also stores comment edit history.
Not sure if that would hold up, as some comments can be pretty identifying. But it's a compromise that a company could try.
