Which websites sold your email the most

Question

I always wished I started my journey on the internet by using one of those techniques to register on each website using a different email address. Some of them are:- Using Gmail plus sign trick (username+facebook@gmail.com)- Using subdomain on personally hosted email server (facebook@userdns.com)- Using a provider that allows you to generate infinite random email addresses (protonmail aliases, Firefox relay....)That way when you receive spam you know who sold your information.What I'm asking you guys is if you know of somebody who wrote a blog post or a report analyzing their personal experience on this topic, and their conclusions.Regards!

I've run my own email server for quite a few years and that's still a tough question to answer. I have thought about creating a few email accounts to test that though, but still not done it.
It would be pretty easy to test that by setting up an email server with a few accounts and make a list of sites you entered those email addresses on. If you entered those email address for just one site you'd nail down the first few they sold your email address to at least and could track who it spread to since.
Mail-in-a-Box makes it pretty easy to set up an email server. It's tough to get a clean IP that's not on a blacklist but you wouldn't have to worry about that. It will receive mail from any IP unless you block it.
