It might be as Louis Rossmann said, it was a mistake to say "we’re going black for two days. They should’ve just says “were going black until you cange the rules again”.

A possible problem is that they would be forced to find new volunteers to run them. While I bet there’s many who want to be “gods” I bet it’s harder to find people who can do it well enough to run a 10+ million forum. Especially hamstringed by reddits lack of modtools.

So sure, Reddit can remove the mods and do it multiple times but it will continuously lead to a worse experience and sooner or later an unacceptable amount of spam, hate and CP will cause the advertisers to pull their ads.
