I'm not sure if I just need more XP to downvote a submission, but really wish I could with this... the whole UX feels slimy to say the least.

You need a small amount of karma before you can [flag] a submission. (No-one can downvote submissions.)

I genuinely have no idea when flagging a submission is suitable. I think it's for when a submission shouldn't be here, but maybe I'm wrong.
