Love the anecdotes at the bottom. I’ll add two of my own:

- Sent myself a photo from a Southern Californian theme park that starts with "D" and ends with a fireworks show, using a custom email address: No third-party spam, but my god their "unsubscribe" links (NOT that I ever subscribed) just don’t work, I got a promotion for everything vaguely Disney-related for a year until I blocked the address completely. Whoops, gave this one away!

- Signed up for a famous freemium file-syncing service whose name also starts with "D" using a custom email address, never used for anything else; that ended up in the hands of spammers.
