@SnowedLightning Thank you for mentioning me on this! I'm bringing in some more thoughts and info on the unlabeled flag here. Fair warning, this is gonna be long. :u
Now, the reason why I included the unlabeled flag is because had seen it used the most as an unlabeled flag, by actual unlabeled people across social media. I want to say especially Tumblr, but I have seen it in a few circles on Twitter and Instagram as well. I've also seen it on a bunch of stuff being sold on Etsy and other online stores among other LGBT+ products. So it at least has actual usage by people who very much identify as unlabeled themselves.
However, there's a few points against the flag as well. For one, the main source that everyone kept citing for the flag design, the meaning of the flags itself, and its creator all lead back to this Carrd. Not a good thing by this wiki's strict standards of sourcing. It would be fine for just getting a high-quality image file of the flag, but the fact that everyone else cites this one Carrd as the source for the meanings and not an actual archive tweet isn't helping.
As a note, I was able to find at least one Tumblr post claiming that this design is definitely used by people as an unlabeled flag, but unfortunately it's on one of those Tumblr-only blogs. So you can't view it unless you log into Tumblr yourself. :/ Here's at least one tweet I was able to find claiming this design as the unlabeled design, so you can see it's being used as such on social media.
Still, the fact that I can't track down the original tweet/social media post of the flag cited on the Carrd is a huge point against it (due to the fact it seems the creator deleted their original account), even if other unlabeled people are still using and spreading the design on social media.
Another point against the flag is detailed in this Tumblr post. Which, again, is on a Tumblr-only blog unfortunately. Long story short, the flag was apparently made by an unlabeled person, but was specifically inspired by colors associated with the content creator Dream and his friends. From what I understand, most of the people in this Minecraft group also identify as unlabeled? I feel it's kind of ambiguous, since many of them don't outright say they're specifically unlabeled, just that they don't want to label themselves as anything in particular.
Despite that, it spread from there due to fans of the group, especially those who were themselves also unlabeled, feeling like they had kinship with the members over being unlabeled. Hence the unlabeled flag being also spread further from there, and the design pops up a lot in fan content of the group as a result.
Which, unfortunately, ties back to something I found while writing the unlabeled article originally: "There is also controversy in forcibly labeling people, especially celebrities, as "unlabeled", which ironically forces a label of sorts onto them". This is basically what happened with Dream and his group members. I believe against their will at that, or something to that effect from what I'm understanding?
Anyways, while their are legitimate and real people who identify as unlabeled, at this point I'm not sure if it's really right to include the flag on the article anymore. Like I said, it's at least very much in use by actual unlabeled people, but it seems it hasn't spread much farther than social media and online design shops since it was made. :/
Probably a big thing is that it still isn't being included on big lists of flags like with some of the major designs (the rainbow flag, lesbian, bi, trans, nonbinary, pan, ace, aro, agender, genderfluid, and so on). Not sure if it ever pops up at actual pride events either, and I imagine the answer is "probably not".
