Any spam I get, I never unsubscribe. Too risky to instead get confirmed as active mail. Instead, those get blacklisted/reported as spam (though I recently found out that this can also leak your email address, fun edit: apparently that’s only an issue with the web.de and gmx.de services).
American companies are great of subscribing you to their spam mails without opt-in.
