@godcock In practise the words ロリコン (rorikon/lolicon) and ショタコン (syotakon/shotacon) refer more to the drawings.
The proper word for "paedophilia" in Japanese is actually "小児性愛" (syouniseiai), and child pornography would be 児童ポルノ (jidou porno) or 児ポ (jipo) if you're in a hurry and don't mind taking more time correcting Fcitx.
