your reasoning makes sense but there might still be comments that aren't even related to Meme Monday in Meme Monday so i think flagging should still be supported there
to implement your request, we would need to be able to detect if something is related or not so people can't just post anything since they know they can't get flagged.
but that is an unsolvable problem since if we could do that, we could basically automatically flag stuff, so no need for any flagging at all
makes sense?
