In the linked incident log, a prominent admin states their opinions pretty bluntly:

"I'm going to simply state this and there will be no argument to it we will entertain. If you occupy the same physical body, chatstaff will be treating you as a single person within our chat. What you do on your own time is up to you. This is non-negotiable. We have voted and decided that no further references [to being plural] will be tolerated."

Since this statement is based on ideas that are just factually not accurate and indicates extreme hostility to further conversation, there's plainly nothing more for us to do here. We'll be deleting our Wikidot account and no longer recommend this community as a safe haven to anyone, plural or otherwise.

They can all rot in hell.

More broadly speaking, this seems to arise from a long-standing frustration with newbies mistaking the site for a roleplay community, and so they have a sort of knee-jerk reaction to crack down on anyone saying things like "I am not human" or otherwise indicating neuroatypicality in a context that is not strictly medical, because they assume that any such is an attempt at childish roleplaying.

This is a fantastic example of how not to handle a persistent community problem:

Get continuously more angry about it over time until the slightest hint of it sets you off and makes your reasoning shut down. Stonewall anyone who suggests you might be doing it wrong, because they're probably just trying to weasel their way out of trouble. Enforce your own thought patterns as the only valid ones and reject all others.

So anyway yes, this has been our "surprise, these people you thought were okay are actually horrible" for hopefully the year

@diodelass =(((

@diodelass I also just personally hopped into chat to ask them for an official stance, and..

I don't know what to say? This is just severely disappointing. I really liked their project before this and I'm just.. UGH

@diodelass Like, from the chat logs I saw of the one system getting banned, they weren't disruptive nearly at all or dominating the chat?? that was just a few lines, chat could've moved on.

not only that but some systems could technically fall under psychiatric recognition because of DID, but not all systems are a result of DID. plus modern science has repeatedly failed to sit down and listen to trans people, people w/ autism, etc., let alone people who experience plurality. demanding official recognition is just a fucking excuse.

@babbage yeah we're out of patience for these idiots

@babbage oh what the fuck, there's some real nasty views on psychiatry here

@diodelass that fucking sucks. I used to like SCP wiki.

@diodelass my knowledge of the SCP wiki is very surface level but I remember there being some kinda split a few years ago where the anti-SJW people created their own version of it (idk what they named it, which is good i guess)
so i would not have expected them to treat people like.... that

@grainloom oh yeah that was when they changed the logo to a rainbow including the black and brown stripes for pride month

a lot of fashy types got pissed about "politics and pc culture ruining the wiki" and went off and made their own shittier wiki

it wasn't that big an incident in the grand scheme of things, they've seen far worse

@diodelass hm.
this is why it should be easy to fork websites....

@diodelass not that that'd solve everything of course, but it would be a nice emergency measure

when admins of communities go bad, the communities should have an escape hatch. i've heard about people deleting discord "servers" out of misplaced anger.

@diodelass I'm worried about what to say about this to a friend of ours who is really into SCP stuff... :x is "the SCP wiki" a distinct Thing from the whole SCP concept?

@Felthry No. they are the very same.
As we have said, this only applies to community admin, not the authors themselves. We think reading the articles will still be enjoyable to us; we just can't participate in the community ourselves.

@diodelass I feel like it's still something they should be aware of though... don't know how to bring that up though :x should I just mention them here maybe or. I don't know, social is hard. Sorry for rambling at you a bit there

@Felthry yeah, worth mentioning at least.

@diodelass sorry for the big necro, but just found out that they had officially changed policy on this to something reasonable by Feb 2020: http://05command.wikidot.com/forum/t-12880038

i didn't find any further relevant public logs for "plural" or "multiple system". (nixie's case hasn't repeated for anyone else. if plural systems have been active in the SCP community since this policy change, they haven't affected public disciplinary reports.)

@bb010g yeah, we saw this. the letter we wrote never even reached them; they just figured it out on their own, probably because they found out that some of their own longtime members were plural.

we still haven't really been back.

@diodelass 🙄 jeez. Double cancelled on the scp forums :(

@diodelass So they don't want me either probably, as a otherkin who is possibly plural

@LunaDragofelis @diodelass the weird thing about this to me is several of the mods are otherkin / trans and usually they crack down hard on people who are being insensitive to neurodivergency issues

@ky0ko @LunaDragofelis yeah, that's why this one came out of nowhere for us

@diodelass so I bet they'd be hostile to non-humans/otherkin as well, now there's a community for me to avoid and warn people about

@diodelass Just now saw your links. That’s a load of horse shit. I will not be supporting them further and will ensure plural users on KM are aware.

@diodelass I don’t know much about SCP or plurality, but it strikes me as kind of ridiculous that people participating in a community around stories about events and things that most people don’t believe in, knuckling down on not believing something many people don’t believe in despite many accounts of it.

@diodelass but then again perhaps it makes sense because they want to be able to strictly draw a line between “made up” and “real” and ignore that brains do a lot of weird & interesting things and the medical establishment lags a long way behind reality

@diodelass Not understanding something is one thing, but prohibiting it is another (shitty) thing...

@pixikamesei yeahhhh we legitimately had to stare at that thread for a few minutes last night, unable to even guess at where the bannable offense was. It just looks to us like
1) person talks
2) person banned for talking
3) person asks why
4) told "because fuck you in particular"

@diodelass and on second thought, "disruptive" is just the ableist icing on the cake. when has that ever meant anything other than "sit down, shut up, and pretend to be neurotypical the way i want you to be"?

@Bisexuhell @diodelass Fucking arsebiscuits the lot of them.

@literallyfenic ouch. yes, thank you for your warning... if only we had seen it sooner.

it's so upsetting to think about all the delightful pluralfolk we know who are really into horror and would probably be wonderful to have around over there

but we guess they don't deserve us if they're going to be like that!

@diodelass yeah tbh

i've been working on my own vaguely scp-esque story thing, i've been thinking about forming some sort of community for it eventually! wanna find a good way to support plural folk who are into writing and reading stuff like that
