I have a very large project that whenever I add users to it sends out an email to all members. To fix this I wrote a command line script that adds the users but bypasses sending out the email. This seemed to be a good fix however everyone still got notifications from inside phabricator and a few people went to unsubscribe. This send an email to all users and created a cascading effect where many people started unsubscribing.

I went to test this in my dev environment and when I unsubscribe from the project I still see that emails are being sent to me when a user is added or when the description is edited. Is this the desired effect or is this a bug or possibly i'm missing something completely.
