They're lazy excuses for actual well-written stories, and deserve to be considered the same way as Zelda, Pokémon and Lost Episode pastas, by which I mean they shouldn't be accepted onto the site anymore.
They all follow the same basic format: "do (scary thing) in (scary place) late at night, and (scary thing) will happen!!!". They are, essentially, an 'easy way out' for beginner writers, after all, it's much easier to write a ritual pasta than it is to come up with an actual narrative.
Now, I'm not saying that every ritual pasta ever written is bad, there are some classics such as 11 Miles that manage to separate themselves from the rest of the garbage, but it seems very unlikely that the genre is going to undertake its own Renaissance anytime soon. Ritual pastas have completely stagnated, and I think it's about time that they are banned from the site.
Maybe I'm being a little too harsh on the genre, but I'd love to hear some outside perspective on this matter.
