I get these as well, roughly once a month. Getting that first E-mail is not too bad; having to sign in to a service I never signed up for in order to stop the e-mail is the pain-point. I wish more companies would require e-mail verification before activating accounts and sending out a flood of messages. It would also protect their customers, because it is quite easy to request a password reset and then, say, go dick with someone's data-populated chat-app settings.
