You can plug all those holes, but your data is still leaking. And wait until Googles new Web Integrity API is implemented. They have a thousand tentacles that are grabbing data. You can cut off a hundred of them, but it really doesn’t make a difference.
You could if you had faith in yourself. My momma always said “Jeff, you could do anything you want if you weren’t so damned stupid”. That’s why I never had faith in myself.
