Just to be clear, this is the same reason that social media companies don't tell you about how they detect spam and they create shadow bans and things like this so that people don't know they've been detected and figure out the mechanims.

And it doesn't work. Even a bit. It's a constant constant cat and mouse game. Maybe they can slow people down slightly, but they won't be able to stop them, and good luck protecting yourself from Elon Musk snooping your stuff in his data centre.
