However, many years ago, I went largely offline, as my meatspace identity. I still do some social media with family, but not in English. And for decades, my work was off the record, doing litigation support. I did edit expert reports and legal documents, but most of that isn't public. And in any case, the style is different.

But sure, if you blog and tweet as your meatspace identity, and then have ~anonymous personas using the same language, stylometry could nail you. There is software for protecting against that, however. And it's getting better too.

See, right there you're narrowing the set by leaking your approximate age.

I don't think your opsec is as good as you think it is :)

But Mirimir in some ways is my least anonymous one.
