@ampzz You shouldn't add kamio_reiji_(yua) unless his face is shown or the pixiv page has 艦隊ジャーナル (Fleet Journal) tag. If it isn't tagged as Fleet Journal, it's just a random Kancolle R-18 fanart. Example: post #2738678 Normally I'd remove the tag myself, but for some reason I can't seem to edit tags on any image at the moment.
Also, when uploading multiple images from the same pixiv post, I think you should attach commentary to only the first image. I don't know the exact rules but that seems to be how it's done.
