Correct me if I'm wrong, but I haven't see @JollyGood ever remove his feedback, it will always stand, the difference is the color he use.

As I always been mentioned by most of users, neutral tag is fine since it doesn't ruin your reputation.

I don't expect he will remove his feedback, but that's just my guess.

You should consider to create your custom trust list, the only way for you to against his feedback is distrust him.
