From the Article: I am signed up to some platform which is a Criteo partner. It’s entirely unclear who this partner is. While Criteo boasts a “close partnership” with Facebook, Facebook claims that they do not share personally identifying information such as your email address with ad partners. Regardless, a platform with my email address gave it to Criteo. This issue is exactly why I use specific email addresses for each website. I tend to follow the pattern <websitename>@mydomain.com. That way if a site leaks my email address to spammers (either intentionally or accidently) I know which site it was, and immediately boycott them in future and move that email address into a blacklist. For big sites I cannot boycott, I simply register a new email address with them (i.e. <website><number>@mydomain.com), and move the original into the blacklist. As I run my own on-premises email system, I can't benefit from crowd-managed spam systems, so keeping a lid on the incoming spam is very much a pro-active action for me.
