Issues: User(s) was unsubscribed and the user(s) said they did not unsubscribe. Multiple 50+ unsubscribes at the same time, which is rare. Questions: The unsubscribe link appears to be hashed, is it possible for someone to maliciously unsubscribe someone else knowing only the target email address? Is it possible to see the originating IP address of the unsubscribe request? Thanks.
