Tangent opinion: going dark will do nothing long term. The mods should walk away, remove all moderation bots and let their respective subreddits be over-run with un-moderated garbage that drives everybody away and makes reddit lose ad revenue. Going dark for a couple days isn't going to hurt reddit financially bad enough for them to reverse their API fee plans.

Making a statement online isn't typically terribly effective at causing change.

My alternative is taking a break from Reddit for awhile in support of the protest and to remember what life was like before it took all my attention.

I've been on https://tildes.net a lot. https://www.themotte.org/ is also interesting.

Go fishing or play golf, would be my genuine advice
