tok.wikipedia.org/wiki/jan_Makuwe

The available self-published sources link jan Makuwe to viba/WhileTrue and contradict the article's statement that jan Makuwe is a man.

1. On the old WhileTrue site, the owner says this is "viba's old website" and that they moved to a new Neocities domain. That ties the old WhileTrue site to viba.
2. On an old page hosted on that site, the author credit reads "A language by WhileTrue / jan Makuwe", linking the name jan Makuwe to the same site owner.
3. On viba's current about page, viba explicitly writes: "I am she or they."

So the article's claim "jan Makuwe li mije" ("jan Makuwe is a man") is contradicted by the person's own identification on their current site.

Notably, the same about page also says viba resides in southern Alberta, Canada, which is consistent with the article's Canada claim and further supports that this is the same person being described.
