Oh and the list goes on. Click hijacking. Redirect soup. 1024 JavaScript tags that record the same events, only they all await each other. CNAME shenanigans. Unsubscribe really means subscribe to 1000 more. Request interception, email interception, email link rewrites in flight, await request to dead dns adserver with no timeout set making your page a hostage requiring closing the tab/browser and visiting page again.
