I'm not gonna say the user's name here, but you'll obviously know when you click this here link to their uploads. They really like barazoku images, but unfortunately, of the 1235 images they have uploaded, only one of them has the tag. I don't have time to do it myself, but I do have an idea of the steps necessary. You'll want to start by excluding the overweight, chubby, and muscular tags as, while these tags are indicators of the bara tag, there are somewhere between 100-250 images that don't have any of these tags and should have at least one. Then, once you've dealt with that and cleaned out the images that have no bara tag potential, you can actually use those three tags as a filter for tagging the images with bara that need them.
