That's why I fractured my personality into 6 seperate entities!

Ironically, one of the most effective methods is to use a local LLM to rewrite your text with a low temperature setting, moving your writing style to the mean of the LLM style. Erase your identity by hiding as a bot.

Wait... Unless your using a local LLM aren't you basically giving all the info your trying to hide to the spying bots?

Humans are not generally capable of such separation. If you do want to do this sort of thing then you should probably use a tool. Of course your tool will likely mark you, but at least it wont lead back to you without the tool. Like the equivalent of blowing out security cameras with a bright LED.
For instance you could use a script that identified all words with synonyms that are used less frequently and replace them with the most common, that removes all spelling errors, that corrects grammatical error, and highlights sentences that run on for editing.
Generally if you want to avoid ID invent a fake person and being that person is easier. Also like, don't share things, don't comment, and ablate all character from your writing (amusingly slop bots are fantastic for removing all humanity from your writing, but general tone analysis tools can suffice).

Interrogation as punctuation? Idk what that is. Commas, periods, semicolons are underused, I have no idea what the former is.

Stay off LinkedIn.

Good thing I've never made a post on LinkedIn. The only thing I've done is search for jobs on there

attacks like this are just correlation/looking for distinct high info signals. Lemmy is if anything even more vulnerable via federation. But you knew that, because you read the article and didn't just reply like a 5 year old struggling against the irresistible call of a marshmellow.

When's the last time you put your real name, current location, employer, coworkers and work history on Lemmy?
naevaTheRat@lemmy.dbzer0.com · 0 pts · 178d
I didn't say that.
Lemmy, and all federated socmed, is much easier to data mine. The way you talk, the spelling mistakes you make, when you post etc can all be used to locate you and demographically identify you and lemmy replicates everything, even posts you delete or edit, to anyone federated.

Getting on LinkedIn don't fix that.

Do you talk to people like this in real life?
ParlimentOfDoom@piefed.zip · 1 pts · 172d
Nice try, AI. Not gonna identify me that way
autonomoususer@lemmy.world · 1 pts · 178d
Cut the personal attacks, like yours on the original commenter, and people in real life will talk to you too.

It's mentioned in the article but we live in an age of anti intellectualism and apparently nobody reads. People have been able to do this with high accuracy for a long time, like at least 10 years.
This just requires less expertise.

Are there any ways to do this for free?
naevaTheRat@lemmy.dbzer0.com · 2 pts · 183d
With a basic knowledge of statistics, some time, and caffeine, all things are possible.
If you mean script kiddie it I fucking hope nobody has shipped that lol

This is a very misleading headline, this isn't really possible with people who use good OPSEC, and yes that means sharing identifiable information on LinkedIn. Also the developers aren't showing their work claiming it will be misused. Which leads me to believe this is a combination of people having really bad OPSEC and also fearmongering.
