What I do is two things

• Go to the All view and block each community that has memes.
• subscribe to commutes that you like.

This ways, all your views are meme-free.

Bonus tip for finding new commuties: create a new account and go to your All view. Every post you see, check if you like the community. If you like it, subscribe to it on your normal account and then block it on your new account. The new account works kind of like check off system. Each community that you made a decision on (subscribe or don’t care) will no longer be visible on the new account. This way, other communities that are smaller will also be revealed.
