You could, and you could even publish those to the blockchain. But the sites/apps that display the content may not honor it. For me, I’d rather not deal with voting.
Honored? You mean display the dislikes? That's all they'd be "honoring".
Correct. If a site uses the upvote/downvote system, another may completely ignore them.
Ok, sure.
Is that a reason to not make one?
