In our Jira instance sometimes users create a filter subscription where some global groups like jira-users, jira-software-users, company-all, etc groups are used in the filter subscription and that sends a unnecessary emails to all the member of these groups that they don't need to take any action and also this cause the performance issues with the mail queue, so we want to setup some alerting when any global group is get added in the filter subscription so that we can check with those users and take necessary actions.
