I swiped reddit's 4chan CSS to add to my personal sub here. On the old r/4chan page, it would show a message that (USER WAS BANNED FOR THIS POST) if you downvoted someone. I tested it out on my page, and when I upvoted a test post with the Fun button, it showed the same (BANNED) message as if it had been downvoted.
Just a curiosity really.
