Seems like whenever someone sets up an "Issue Subscription" email, they select the entire Jira community; however, most of us are not involved in their project and have no way to opt-out of those emails. It's annoying and very time consuming to get removed from the list, or to have the distribution of these notifications updated.
Every Issue Subscription email needs to have a mechanism for people to opt-out of receiving it. At very least, the person who set up the notification emails needs to be referenced at the top and bottom of the email so users can quickly and easily flood their email box with requests to unsubscribe from the notifications.
Additionally, nobody except system administrators should have the ability to add "all jira users" to any Issue Subscription distribution.
