I tried the Critiquebrainz "was this review useful?" rating function for the first time today and after I had clicked Yes, I was confused to see that the No buton was greyed out whereas the Yes button still looked active. It made me think I had mistakenly clicked the No button when I had meant to click Yes, because the options presented (not greyed out) now were Yes, in case I wanted to change my rating, or Delete rating. So I deleted my rating and clicked Yes, only to find that again the No was greyed out.

I suggest changing the user interface to make it more clear as to which vote the user has submitted, and simultaneously making both vote buttons inactive after someone has voted, as long as the Delete option stays so that someone can still change their vote if they want.

For reference, the review I voted on is here: https://critiquebrainz.org/review/d6920056-1dd9-4c36-8476-7f8625ce9b82
