I have no problem for any author writing whatever they want. In fact i wish their status could get better, because they suffer 0 or low income despite writing very good series (unlike in jp/china)
Its just that "bag tagging" is quite annoying. Go look at pixiv, in futanari. You can get futa x man but author only tagged "futanari". Or you want a yuri series, sometimes they use "GL" or "lesbian" but not the tag "yuri"
NOVELUPDATES have the best tagging system ever, but no one else try using it.
