LunaStar77 I have the guess that they had to avoid willing to host lesser-known and unusual queer labels due to the concern that they would otherwise accidentally host a satire/joke/unreal/misinformative/invalid label, and also due to the concern that someone might use a lesser-known/unusual label with limited resources about it, thinking they identify with it, when it turns out to actually be a wrong identification of their identity.
They couldn't just check if the coiner said their account was a satire/joke account to determine if the label coined by and posted on it is satire, because if the coiner pretended to act "genuine" and "normal", but is actually a satire one, Fandom would have likely made the wrong assumption that the label would be considered genuine. The label would have to have research in a highly reliable, accurate, and trustable source (e.g. a book approved by the highest-trustability level of academia, a long-standing non-commercial organization, an academic institution, a research institution, etc.) where it turns out to be a real, valid, and genuine label and individuals know whether to identify as it.
(Warning: mention of radqueers and a satire fart-related sexuality) They also couldn't just rely on reviews of a book along with simply relying on books that mention the label, because hypothetically, a radqueer person might create a book that is designed to "validate" satire identities as "unironic queerness that should not go through hate", like "Fartsexual is a valid paraphilic sexual orientation where you are sexually attracted to farts, and invalidating it means you're a fartsexualphobe bigot!" (Fartsexual is made by a satire DeviantArt account), so if that had many positive reviews that may have been from other radqueers and children who did not understand that the book contains invalid information, then if Fandom simply relied on whether a label is mentioned in a book, along with peers' reviews of the book, it would likely get tricked into believing the identity is valid and genuine.
They also couldn't just rely on the popularity of the term. Hypothetically, a coiner of a satire term can intentionally spread the popularity of the term and could have tricked Fandom into believing the term can be put in an LGBTQIA+ Wiki page, by pretending the term is valid, posting about it multiple times, and having multiple people unironically identify with it without realizing the term is actually satire.
(Warning: mention of bird death, reproduction, and gore/violence-themed xenogenders) I believe that the reason why they hoped the wiki would find a new wiki host to migrate to (despite saying that they believed individuals need high-quality accurate responsible sources to figure out their gender) was not just that the new wiki host might allow gore/violence-related genders, but also that the new wiki host could be analogically similar to the concept of a bird nest combined with the context of natural selection. Think of the migrated version as a nest where there are many hatchlings on it, and the LGBTQIA+ Wiki as the current gene pool shaped by selective pressure. Some birds will survive and reproduce, but others will die. Similarly, certain genders on the WikiOasis wiki might turn out to be unreal or satire, and it might be currently unknown if they are, since they have limited resources about them, but only other certain genders could make their way to the LGBTQIA+ Wiki if they have reliable pages of them where they turn out to be valid and real.
Do you have the same guess as mine?
