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.
JollyGood has removed a red tag or 2 during his tenure here.
You should consider to create your custom trust list, the only way for you to against his feedback is distrust him.
Just because the OP won't see the feedback anymore, doesn't mean it just disappears. The rest of the forum will still see the neutral. You are correct in saying the neutral doesn't mean much.
@OP you might consider just letting it go and locking this thread. The feedback is neutral and means very little. At worst it will make a manager look more deeply at your profile when you apply for a sig campaign. If you are putting effort into your posts, you have nothing to worry about.
