It's not really big players per se, but "domains with a lot of users that I can't block". Which of course means "big players" for regular people. I agree with

It's not really big players per se, but "domains with a lot of users that I can't block". Which of course means "big players" for regular people. I agree with sibling that the problem is with Email marketing, but for different reasons. Companies are so addicted to spamming users and selling user data that it becomes unacceptable that users might not want to give away their email. Another problem is emails being required for signing up to accounts. Honestly IMHO we gotta get rid of email for signups. I don't know what to replace it with. Hardware keys, maybe?
