One of the reasons I love my catchall email is catchall + password manager* throws a wrench in a lot of tracking. Even if you don't use Oauth, a commmon technique is to hash the email and compare the hashes. You can strip out periods or plus signs (ex: dontbenebby+hn@mydomain.com) but it's hard to track a person who gives a unique username, email, and password to every site. (Though I guess they could intuit I'm the only one who uses my custom domain, but that'd be hard to do at scale) *use PW manager because each site needs a unique PW
