Reddit is sending strongly-worded messages to moderators of certain subreddits that are marked as NSFW (Not Safe For Work), telling them to remove the tag or face being removed.
I wish people would take a more subtle approach. Have a pinned post saying that mods have moved the community to the lemmy one with the link, and have a bot reply to new posts saying the community has shifted and how to post there with a few linked resources. I’ve seen this strategy used successfully in many subreddits to get people to discord or some other platform.
I remember when the female dating strategy sub did this rather successfully.
They were about to get banned anyway for the incel-like behaviour and took it upon themselves to switch platforms.
