These days I mostly use unique addresses, unique passwords, and where possible MFA to secure my accounts. Reduces the risk of brute force attacks and other weak account compromises.
Historically though my intention was to track who sold my email address and combat spam. It worked great.
The most notable one was the address I registered with ISC2 when signing up to take (and pass) the CISSP in 2002. The unique address I gave ISC2 and only ISC2 in 2002 was used to send spam and scam email not long after.
It was a fairly common occurance in the early/mid-2000's to receive spam where I registered addresses. These days it seems to happen much less.
