Going into a club just to go around showing everyone a thumbs down is being an ass tbh. I can’t say whether there’s a rule against it, but it’s not behaviour that’s helpful for anyone.

For stuff that shows up in your All feed, you can downvote the post to keep it out of others’ feeds. If such posts appear too much you can block and move on. The mods have just done the latter for you.

YDI. report dangerous content (which i agree this is) to admins for moderation or defederation.

but blanket downvote trolling is a real issue that any community mods should be allowed to address.

I mean I get it’s annoying. I also think “carnivore diet” is just a dumb grift like “raw milk” or whatever. But I don’t think you have a right to complain here. Someone created a community for people following this diet, it’s obvious they will ban anyone like you who is vocally opposed to the diet.
