Here's a general primer https://programminghistorian.org/en/lessons/introduction-to-stylometry-with-python

It's ultimately just statistics, and AI is far better than humans at finding patterns in massive data sets. They are perfectly suited to stylometry. The more text they have of a given user, the higher the probability of cross-referencing against identified users (Facebook, Twitter, etc).

Even if you never post publicly, the problem is western governments have been engaging in dragnet mass surveillance for decades, which means the US gov — probably many govs, especially your own — almost certainly have every text message, email, etc you've ever written; all are transmitted unencrypted. This means the US, and likely your own gov, have the highest probability of deanon-ing you. They also have the highest budgets ace access to perform such a task.

Again, it's only a matter of time until 99% of "anonymous" accounts, above a certain word count, are cross-referenced; likely only a few thousand words. I suspect they could already do 99% of accounts above 10 or 20k words.

Then you don't understand how mentally ill and authoritarian the surveillance state, or fascists, are...

They already have dragnet data capture going back decades. Hundreds of billions spent on data centers. The process can be entirely automated, and will be, soon if not already.

It’s not like it requires much effort for the government to do it at scale.
