I'm not sure they can. What can they do? I doubt they'll replace moderators with paid Reddit workers. The alternative is to replace them with other power hungry moderators who will bend a knee to the Reddit admins. That might work on some major subreddits but the PR of that might cause more damage.
I think the admins hoped it would have blown over by now. If it's still going on by September I bet they'll need to do something.
