Confirmshaming

Confirmshaming is the act of guilting the user into opting in to something. The option to decline is worded in such a way as to shame the user into compliance. The most common use is to get a user to sign up for a mailing list, and it is often found in exit intent modals and other popups. In the screenshot below, Google uses confirmshaming to discourage users from opting out.
