#2I was thinking about this recently, couldn't you alter one word in message to create two copies, and then basically perform binary search until you find the person?

Yes

#4Clever but easy to work around now that everyone knows the trick.

#5Now that this is known they'll need an approach that can survive retyping, like word choice and order. That can be defeated by rephrasing but requires even more work, and is somewhat identifying of the rephraser.
If you find a corporate document with a lot of weird sounding word choices and ordering ... it's probably just written by someone not great with the language.

I believe Tyrion did this trick to find out who he could trust while he was serving as Hand of the King.

#7What if someone spottet some space characters and deleted them?
I do if I see double spaces.
Or is it about printed documents?

#8Why do people still work at Tesla, or does this toxic behavior attract toxic employees? I guess that seems to be the case, if you read about Uber under Kalanick, or employees crying in bathrooms at Amazon.
Before that tweet the thread is talking about an email Musk sent:
> Scoop: Elon Musk just sent an email to all staff outlining "Twitter 2.0", writing it will"need to be extremely hardcore". Long hours, high intensity.
> People need to click "yes" to confirm being part of this by 5pm ET tomorrow, else they get 3 months severance. [...]
Hah, "Click here to agree to a toxic workplace, or be fired"...

It's called a barium meal test, or canary trap.

There are thin spaces, hair spaces etc. in unicode.
Multiple of those will just look like a normal space.
Only if you tried to select them one by one would you become aware. But that's not what people usually do when they C&P a block of text
That said: not sure how they will look in a text-only (no WYSIWYG) editor or a mail client set to display raw text.
