It'd be nice if it were possible to automatically flag as spam any email from a distribution list for which I used Proton Mail's "Unsubscribe" feature to remove myself from the list. The idea is that if the list owner is not going to honor unsubscribe requests, and since I already indicated that I do not want to receive those emails, then the emails from that list are spam and should be treated as such. An automatic method to take care of this would be handy.
