Maybe. It depends on what internal controls they have (or don't) and whether it was evident to other admins that the comments had been altered.
There's a lot we don't know without knowing the internal workings of Reddit, though I agree that you can't have to think that if one rogue person (even someone like that) can just do such things, they don't have robust internal controls at all.
