oh yeah. i was around when they were making that wiki. everyone on that discord was an absolute piece of work. one incident i remember most clearly off the top of my head was one where the og creator of the sexypedia ("ironically" obsessed with the onceler at the time-i have no idea if it's still the same person by now or if they handed over he project to another person, but if they're still doing the horny police five-seperate-giant-banner-warnings-over-every-page-warning-you-that-everything-about-this-character-and-their-creator-is-Problematique thing it's probably still them) started going on about how they hated using "a service called fandom" (the wiki was originally there, evidently moved to miraheze years later after i stopped paying attention) specifically because the word fandom is dirty and they don't want to be associated with it, because they think of fandoms as being "weirdo freaks", and went on to talk for several minutes in half-joking-but-kinda-unsettlingly-not-really tone about how the word fan/fandom is a slur ("the one slur" in reference to the onceler). the very next day (iirc-it's been years, and the original discord all of this happened on is almost certainly not around anymore) the people of the server started openly, very genuinely planning to launch a mass vandalism attack campaign against the onceler wiki(which as a thing apparently???) because one of the many onceler fan-variants it documented was the "wendigo-ler". i don't know if they ever actually went through with it, but i know they were very serious and genuine in their desire and plotting to do so.
nobody ever got much of anything done on the actual sexyman wiki side, they mostly just sat around purity-policing eachother, tepidly suggesting new wiki additions in palpable fear of being nuked for possibly accidentally suggesting something the owner deemed Immoral, having weirdass sin confession sessions where they all ritualistically outed themselves for their past problematic(tm) fandom-ing, saying cringe is dead, and then talking about how vile everyone outside on the rest of the internet/all external fan-spaces is. they seemed far more interested in trying to find the next cancellable Freak of the hour and making ironic-but-not-really jokes about the hotness of the onceler than in actually running the damn wiki or getting anything updated. the only time anything on the wiki ever really seemed to get done was when someone went rogue and just started fleshing out things themselves (there was supposed to be some system i don't recall the specifics of where you had to pitch an idea and get an arbitrary number of votes from official important team members or whatever, but in practice none of them bothered ever actually weighing in on anything and so that just never got done, and even when something was nebulously approved by the general consensus for addition almost nobody ever actually got around to doing it. the suggestions system, whatever it was, was so dysfunctional that after they moved it off the discord and onto the actual proper wiki's discussion(?) page it eventually just devolved into people suggesting any random obscure character they personally found attractive anyway), which would invariably be neutered by the moderators in the next edit because we can't have literally any references to people's attraction or fanfiction referencing such in a sexyman wiki, because "the children might see it". i also just- and i don't have any specific memories to back this up-but i just have this vague recollection of having somehow gotten like a... vaguely, almost terfy vibe to the place. i don't remember why. again, i don't have any specific memory i can point to for that. i think there was a huge schism at some point during the couple of days i was there where a huge number of the server and team members were kicked out for Fandom Drama Reasons I Don't Remember and it had major toxic friend group breakup over callout post type energy, which is appropriate because i'm pretty sure all the main staff were the creator's friends.
the original creator of the wiki also had a hyperfixation sideblog (long since deleted now) where they would constantly talk about the onceler, tumblr sexymen, the wiki, and answer asks, namely to rant about how they think everyone who ships wrong or writes the wrong kind of fanfic should actually literally graphically die. i remember one specific ask in particular, where the asker said something like "so you're saying if you see a kid playing with dolls in a way you don't like they should be killed??" and their response was basically almost exactly "literally yes". and in context it was very clear they were not being sarcastic about it. they also had a drawing of evil alternate universe sharp-toothed emo badboy pleakley lilostitch, which is the only other specific thing i remember off the top of my head.
i want to emphasize though that this was all years ago and i was only in the discord chat for around 3-5 days, and was only a contributor/vaguely paying attention to the wiki for something like 5-6 months (and i spent the entire two and a half years those 5-6 months were in mostly in a severely suicidal borderline psychotic haze, hence the wasting time contributing to a badly-run novelty wiki helmed by toxic lunatics. being unable to stop hysterically crying whenever awake for that long gets boring as hell, i needed something to do that wasn't wall-staring).
