I also do unique aliases for each account I have. Few of them have been a source of spam. I also have expiring subdomains. So I'm not using domain.com, but something like b2.domain.com. The rationale is that if I start receiving a lot of spam, I go through all the accounts I have, change all emails to use another subdomain like b3.domain.com, and then invalidate the old subdomain entirely. I haven't had to do that yet and my domain is several years old. With two big exceptions: the email address I leave on my website and the email address I publish on my GitHub profile. These 2 have dedicated throwaway domains like throwaway283728@domain.com. Because you wouldn't believe how much spam I get from that GitHub profile, not just recruiters, but also get rich offers from princes in Nigeria and Viagra pills.
