With the constantly changing number of members, my thought would be it would be a lot to ask the CSG staff to be able to keep track of the multiple accounts for any one user. I can see times when one might want two accounts, as when uploading models that fall in two distinct categories, but that would be rare.
I have one now that seems to be what I would call stalking, and charmy only knows the one star. Big deal, a better guide is how many downloads to how many views.
Not that I can go back before the site was keeping track of the ratings, but looking back and seeing the same name consistently gives a pretty good hint as to why the rating suddenly dropped.
Why people think they have to do things like that, I have no idea, but a mental deficiency is definitely evident. I've seen some very nice work given a lower rating that it probably should have, what anyone gains from that is beyond my comprehension.
