It's a surprise it took this long for someone to care about it then but I see your point, I won't remove it from valid posts.
I think perhaps because of the frequency by which it was purged, that when a tag someone would like to use doesn't exist, they just move on. I notice a tendency of useful tags like the one being discussed getting eliminated, simply for being a new tag, and not on the basis of their merit. I believe some users as a custom delete new tags, particularly in monitoring the new and repopulated tags report. I warmly suggest that more discussion like this could be had, rather than moving first to eliminate a tag because it's not understood in an instant without more consideration or discussion.
I have encountered multiple situations while artist gardening where a post actually did have the very same name of the artist entry I was trying to create, having been applied by the uploader but removed by another user, corresponding to the tag showing up in the report. The uploaders were probably either not knowledgeable in making their tag an artist tag and populating an artist entry for it, or they made some understandable mistake (I've heard it said that humans make over a hundred a day, and I certainly make plenty myself) which was left unnoticed, I use this just to serve as an example.
