Unless the Reddit admins change their tune, I seriously doubt this will be a few days. It’s entirely plausible that the site implodes over the course of a few weeks.

Besides the political fallout, this API change will fundamentally cripple most of the tools hacked together to moderate the most popular subs.

Without the means to operate at scale (including many valuable bots), the volunteer mods who choose to stay will probably slowly drown under the sheer scale.
