I think the color of the feedback should be changed to neutral. The wordings are probably correct, but they do not deserve a negative feedback for it.
It's more appropriate to change the color, but I don't see the point/effect after that.
BADecker would still have 3 red tags, while sharenet914 has no value given to the forum and likely won't back to this forum.
So I don't take his other tags seriously, in other words it's still fine.
So what, mate?
You shouldn't tag someone incorrectly just because they already have some tags or they are not active anymore. Your logic is like, a dozen people throw their trash bag in the pond, and if I refrain from throwing my trash bag, it doesn't change much. Because some people have already thrown the trash bag, and there are no fish in the pond. How does that sound, mate?
In my opinion, it doesn't really matter what others did. Listen to your heart and do what you think is good. If you know that it is not good, please don't do it. If I know I am doing something wrong, why would I do it?
