I have users that used to collaborate with us in JIRA and JIRA Service Management. They no longer do, but they need to report issues, as a reporter, and receive notifications. Problem is, they are officially "suspended" and can't be added to issues as a reporter. So no notifications, and no way to delete them, add them, only to activate them, as if they are a JIRA service management user, which makes no sense (free limit is 3)
