Good point @nbaksalyar, and this shows how difficult opsec and true anonymity are.
On the other hand, people have tried stylometry attacks to unmask Satoshi by analyzing the bitcoin whitepapers and source code, without any conclusive results. Either “Satoshi” is multiple people, or these kinds of attacks work really well for fiction (as seen with JK Rowling) and less well for code or technical documents.
There’s a program called Anonymouth that purports to be able to anonymize one’s written output to defend against these attacks. I tried it a couple years ago but couldn’t get it to run without erroring out.
