Couple funny stories about Elsevier. I published with them, and created an account. They started sending me spam advertising new journals. So I logged in and unsubscribed from all their mailing lists. Reliably, exactly one year after unsubscribing I get spam from them. When I go to unsubscribe I find a new category of mailing list, opted in automatically.

One might call it a mistake, but is remarkably suspicious that the spam regularly arrives exactly one year (to the day) after I most recently unsubscribed.

There are the financial aspects to their exploitation, but I guess this struck a nerve because it is scummy behavior that affects me more personally.

As a possible hypothesis test, next time, could you leave the new opt-in in place for a month before unsubscribing?

If that reliably then has a new list added exactly one year later, it is a strong signal that it indeed based on you unsubscribing. But, if it instead happens at 11 months, it is a string signal that new lists are added at a specific month/day.

I mean, I would not be surprised if it happens one year later, due to Elsevier tracking when you unsubscribed, but this is a testable hypothesis, so testing it would be a Good Thing.
