When I contacted Substack about it they insisted that I can't be subscribed to a mailing list there unless I gave them my explicit consent. Quickly going through their own documentation I found out that this is not true: Substack allows you to import CSV subscriber lists without the consent of each subscriber, ostensibly to allow painless migration of old mailing lists. That feature is of course abused, and they did nothing when I reported the abuse, presumably because spammers represent a large part of their business. What a piece of shit company.
