Confess your e621 sins.
1) When uploading images by artists I sometimes stumble upon images that have a high upload worth but aren't interesting for me. Like solo female images. I often upload them, tag them lackluster and put a tagme tag on. Then I don't see anyone fixing it a few days later and do it myself.
2) Sometimes I don't recognize the species. Like when something could easily be a wolf or husky. And I don't know about all those cat species. Then I just look what the artist called it and take that as tag.
