Proposed the downvote button multiple times and people did not like the idea!

what about a "swipe cast away" action that bumps a cast from your feed. doesn't have to be displayed on the cast itself and bonus is that it could be used for personalization e.g. "predict likelihood cast x will be hidden by user y". I think low friction of the action would make people use it and seems high-ish signal
