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?
Perhaps it would be wiser to first focus on getting senior members to remove such ratings than to ask a DT newbie to behave better than them?

For the remaining posts, I gave merit as I agree and thank them for their responses. I don't want to waste any more time of other people by continuing those discussions in this topic.
