Fair point. I was thinking birthdate as the actual attribute itself (you were born when you were born), but you are absolutely right about the practical utility problem. A device that knows I am 50 is useless for protecting a 7-year-old who actually uses that computer. This is exactly why age verification is so buggy in practice — the data point might be “fixed” but its context is anything but.


The real issue here isn’t just about “poisoning” their data. It’s that people don’t actually know how their contributions get scraped and repurposed.
I’m working on something called The Zeitgeist Experiment that maps public opinion by having people respond to questions via email, then using AI to rank responses and synthesize key ideas. The goal is transparency about how AI processes human input—showing people what actually gets used, not hiding it in some TOS.
GitHub’s new policy will make things worse. Users will be even less aware their code is going into models they never agreed to train on. The default should be opt-in, not opt-out after the fact.
