X permanently banned my 15-year-old account for sharing my own open-source lib

The post itself was fine. Then I replied to it with the GitHub link and three hashtags (#creativecoding #threejs #webgl). Shortly after, my account (@dzhumagulov, registered 2011, no prior violations) was permanently suspended for violating the X Rules — moved to read-only, can't post, like, or create new accounts.

I appealed through the official form: explained it's my own MIT-licensed project, no monetization, posted once. The rejection came back from their automated system, and the template literally didn't name the violation — the "specifically:" section was empty. It just says the decision stands and I should "remedy the violations," without saying what they are.

So the current state: banned by one automated system, appeal denied by another, and no human has told me what rule I broke. As far as I can tell, "external link + hashtags in a reply" simply pattern-matches to spam.

I get that spam detection at X's scale is hard. But sharing your own open-source work is about the most normal developer behavior there is, and there's apparently no path to reach a human reviewer. Curious if others have hit this and whether anything short of going viral actually works.
