it isn’t just /c/memes looking at the global feed I felt like I was blocking meme related communities for a while yesterday.
I think the core app needs some simple text filters for communities and posts or hopefully some of the client apps will implement that a number of the meme subs at least have the word meme in their name.
Same could be said for NSFW subs, but we at least have a global toggle for those at if they have been correctly tagged.
