The thumb icons are small, though the "down" color is opposite of "up" it looks confusing to see "Good site" when > > you hover over a down-voted comment.
Leaving the icons as they are but expanding the hover text to:
Thumb down: "You disagree this is a" + "COMMENT CATEGORY"
ex: You disagree this is a Good site"
ex. You disagree this is a Scam site"
Conversely if you agree and see the thumb up icon
Thumb up: "You agree this is a" + "COMMENT CATEGORY"
ex: You agree this is a Good site"
ex. You agree this is a Scam site"
Expanding the links title should be simple and might ease language translation as well.
