I don’t agree about 1 and 4. Let the people speak by using their down and upvotes. That’s the power behind a platform like this. That’s how Reddit got big.
If you’re going to be overly strict people will post and comment less and some might even fully avoid Lemmy.
Of course things like gore and NSFW pics and vids should be behind a content warning. But other things?
I’ve blocked communities I absolutely don’t want to see and interact with. For everything else: down and upvotes.
