Haha, i was able to dox myself by asking "what is the real name of user mnky9800n". TBF, i don't hide my real name from this username. but still, it just churned until it decided it was me.

At some point, in response to someone describing another comment as made by "a random anonymous person on the internet", I said "I don't have my name in my bio but I don't think it would be particularly hard to find out who I am."

But it's different thinking that, and having the LLM actually come up with the right answer so quickly. :-)
