I'm not sure e-mail selling is as rife as it used to be. Starting in 2003 and up until 2016, I used a catch-all e-mail address and would sign up for everything using a custom e-mail address. I wouldn't even do in the form of "sohcahtoa82+service@mydomain.com", I'd just do "amazon@mydomain.com". The only spam e-mails I got that were e-mail addresses I used were from a couple shady cryptocurrency mining pools, a forum that got hacked, and the e-mail address I used on USENET. I also got spam sent to <random hex digits>@mydomain and lots of <two random dictionary words>@mydomain. Knowing how much spam came from my USENET e-mail address (which I eventually changed and black-holed), I wonder how many spammers are scraping usernames from reddit and just spamming username@gmail.com.
