This too, this would be ideal, and its actually what makes both IB and Weasyl fail imo.
Furries just have never been very good at tagging in my experience.
Weasyl's solution that other users can tag is decent, but it falls short in that it sometimes causes controversy and there are not enough people on Weasyl. I can't remember if IB has this feature, but if it does, I'm willing to bet there is a fair amount going untagged just because of the "normalcy" factor.
I'm willing to say maybe my bad experience on IB was during the early years, and perhaps its gotten better, but I do think some other people had a valid point that not everyone wants their own work surrounded by the stuff.
Of course, at that point, you need to be smart and invest in your own nicely done portfolio on a web domain you bought. And not have only furry shit in it, ideally.
