Not him, but a few examples I can remember are
There was some dude who crossdressed as one of the older characters, complained about neighbors in the thread, lived with his parents, and pissed on a cat.
There was another guy, Filipino, with a twelve year old girlfriend who spammed threads with the rule 63 version of the main male character.
There's the people who avatarfag for no real reason.
The people who drawfag'd for the threads then all left for a discord, and the dumb drama that ended from there.
The obsession with original characters that all stem from the obsession with incest shipping.
And other dumb shit, and that's all just from the /trash/ threads.
In general, you could also point at people, like on tumblr, who policed people who were for incest and the people, who I'd say are just as bad, who id the same or force incest down people's throats.
I love the show, it's legitimately good with quality animation, good jokes, and lovable characters if you aren't trying to pass it off as something that it's not, but some people into it just don't seem right in the noggin.
