Ah, you meant those subreddits. I thought you meant the ones on strike - I think of the /r/fatpeoplehate thing as a separate, prior incident. That's also not really at all Victoria's department; my understanding is that she really only did AMAs. It was just a recent time the community got pissed off at the reddit administration (and therefore Ellen personally, because CEO), so obviously it fed the flames some more once the Victoria trigger happened.

Victoria wasn't involved in those subreddits being shut down by the admins at all, as far as I'm aware.
