There is currently very little activity in the group. This type of group gets a lot of traffic on other social media platforms. There is only one mod listed. The last post that they made anywhere on Lemmy was 11 months ago. I can help revive this group.
each instance has their own rules and different admins, you can’t expect lemmy.world mods to make changes on a lemmynsfw.com community. As a different example, I am the admin of lemmy.bascul.in but I can’t change the moderators in a community hosted by lemmy.world.
On their site, the admins and contact information is visible here
