It's speculated that the alternative flag of fruitgender is made by the deleted X (formerly Twitter) user Izumiikyouka. Despite the account now being a 404 page, it's still possible to find evidence.

Thanks to an archived list, we can look at 785 tweets made by the user, from oldest to newest. I had enough stamina to check the first 100, but I still need your help because none of them contained the word "fruitgender" as far as I know.

Please let me know how many links you're checking (e.g. to the 101st to the 200th) and share any of them that contain the word "fruitgender", regardless of whether an image is attached or not.

I hope we find proof that the fruitgender flag is made by Izumiikyouka, because many netizens take any information on a Wiki to heart even if a citation is missing.
