Someone could probably find a way to stop cloud chats. And they're not that common anyway.
So far, no one's found a way to prevent people from creating cloud chats. The only way is reporting them for takedown after they've been created. I guess until then, cloud lists will stay rejected.

As for them not being common, that's kind of the purpose of rejecting cloud lists. Because it's currently so difficult to create a cloud chat without cloud lists, there isn't too many of them. And just because something is uncommon, doesn't mean that it should be allowed. Although profanity only makes up of 0.5% of what people say, that doesn't mean it should be allowed on the site.
