I've been using a catch-all domain with unique addresses (example: ycombinator@mydomain) for every service/site/etc. for more than 10 years.
Surprisingly, none of these email addresses have gotten spam, outside of what the original service sends.
As someone else mentioned, most of the spam I received comes from people with the same name as me. I was an early gmail adopter and my gmail is my firstnamelastname@gmail. I get spam, people's rental agreements, dating profile information, mortgage closing papers, etc for people with my name from across the country. There is someone who has been convinced they can create a gmail with my firstname.lastmail@gmail who has signed up my account for facebook, netflix, and espn+. This is much more of a problem for me.
