There might be reasons. For example if a long standing, highly trusted account gets hacked, it's useful to get the warning (orange color) after a single feedback, as that can be quickly left.

It doesn't give you very much credibility when you are going around giving extortionists positive trust. It doesn't give Cyrus nor HostFat very much credibility either if you remain on their trust lists.
