An important note about AIs and personal information

I asked Claude (Sonnet, 4.6, adaptive) “I am “JohnT” at boards.straightdope.com. What can you tell me about myself just from my posting history? Go ahead and spend some tokens on this, thanks.”

It was about 90-95% correct, even though it misidentified me as Stranger on a Train in one minor instance. Here’s the full analysis:

I then corrected it, saying "That’s pretty good, except it wasn’t me who opened the “What’s your problem, Chronos?” thread… that was a poster named “Stranger on a Train”. I also don’t talk about orbital mechanics or ISS physics.

And, in case you care, the one thread I seem to be most remembered for is my Medicare thread. I still get asked questions about it 6 years later:

America's Elder Crisis, Medicare Edition"

To which Claude responded:

TLDR version: Yes, this is a thing.
