As anyone on the site will tell you, the "Tag what you see, not what you know" rule is beyond retarded. And the majority of arguments over it end with some mod coming in and "Telling" us what's what. The thing is the artist's authority should be higher than anyone else's. Because he knows what he drew. A perfect example of this would be in http://e621.net/post/show/257254.
Anyone with a brain cell could easily tell that that is Rainbow Dash. Blue coat, artist's background on ponies, Rainbow Colored pubes... Jrvanesbroek, the artist of the picture, even said it was Rainbow Dash when he posted it on his tumblr. There, you have the artist saying who the picture is of. But, for some reason, that does not apply to this site. The rules on Tagging are flawed and need to be changed. Not ignored.
