The Loud House fandom. Which, i'll admit gets a bit of a bad rep, but a lot of it is pretty weird. It has some of the usual problems that other fandoms with very young fans have. You know, the kids who can't respect opinions, harass each other over petty stuff, etc. But also, some of the older fans suck too. There are adults who complain about "cringy" fanart even though it was made by someone less than half there age. Plus, there are incest shippers (bare in mind the main cast consists almost entirely of siblings), and well, most of the main cast consists of a huge selection of pre-pubescent and teenage girls; you can imagine some of the people who would be interested in this show.
