That is a truly insane amount of moderators for a forum of this size.
At least half of them are inactive or barely active.
Has Mikado transitioned into "this forum is too boring/I don't care to post but I still visit it out of habit" phase?
Nah, he's less active than before, but still handles some mod reports. Not as many as Inks though. Here's a list of every mod who's handled at least one moderator report in the last two weeks:
Al (but only to remove the points that Inks gave him)
AndrewCT
badger
Ernest
Gustaf
Inks
The Mikado
Mr. Moderate
Mr. Morden
nym
Torie
Of course, there are other mods, like Beet or Tender Branson, who are active posters but just don't have to do that much moderating (at least not at this time of the election cycle) because their boards are either not that active or pretty well behaved and hardly anyone ever reports anything. Bacon King is another one who has been very active in the past, during the 2012 campaign when the 2012 board's traffic was enormous, but just doesn't have nearly as much to do in odd numbered years.
