There is something called the "Crunchyroll Store". I don't know what they sell, I assume anime. On Oct 22 they sent me an email titled "Oops! Thought you'd ghosted us!" and, starting at this point, started emailing me heavily, a couple times a week, leading up to Nov 19 since when they've been emailing me every day, sometimes multiple times a day, with spam.

On Dec 3, I unsubscribed. The daily emails continued coming. I filed a support request and was told unsubscribe can take "up to week"
