I’m not on Reddit, but I heard that some NSFW subreddits became Christian subreddits, and some SFW subreddits are filled with porn and other stuff (for example, r/interestingasfuck (Interesting As Fuck) became r/interestingasfuck (Interest In Gas Fuck)).

Reddit forces subreddits open, so some subreddits continue protest in different ways.
/r/pics only allows “sexy pictures of John Oliver” and many others follow suit. I know that at least /r/interestingasfuck started allowing porn, because Reddit cannot monetize nsfw content, but I don’t know if any more subreddits did that.

Mods have turned their subreddits into nsfw subs as reddit can’t put ads on those subs.

Afaik, r/pics is only allowing picture of John Oliver and r/interestingasfuck is abusing NSFW tag.
