You're stepping well outside the bounds of your analogy. Incoming email is like a social media feed, hence the comparison. It fails when you compare things like shadowbanning with spam, as I pointed out.
Going out onto the "dark corners" of the internet though, that would be equivalent, perhaps, to signing up for an equivalent email provider without a spam filter?
Nope, that doesn't work. Hard to tell what you could mean other than "my initial analogy didn't work so I'm going to move the goalposts".
