Don't Sell My Personal Information
There's a small note in footer (or another places you probably never look) on some websites that offers you a form to complete (with your personal data of course) to ask them not to sell your personal data.
Keeping personal data private (and not storing them at all) is basic right. Privacy is basic right for humans and we should not fill forms to stop corporations collecting/selling them. Privacy is not a luxury, it's a right.
