I believe he just enjoys it, perhaps because he does not consider it important. Though I agree with your imprecation so long as the hiatuses are concerned.

Anyway, I'd much rather keep it as it is now, perhaps substituting them/their with Neferpitou's name: even the One Piece Wiki has done it with a character, and it is one of the best and most prolific wikis around (that's because Oda is a Stakhanovite and it has thousands of contributors).

However, if we decide it is not possible, I'd rather designate Neferpitou has a female character. I still believe Neferpitou is male in the manga, but I am not entirely sure, and in the anime Neferpitou is almost certainly female, so, if we can't do like the OP wiki, this is my position.
