Normally, I'm getting less then 300 notifications a day (I'm never reciving mails, only notifications). I'm getting a lot, because I'm watching a lot: https://phabricator.wikimedia.org/project/query/idZQrOAW9olX/#R
But if @Phabricator_maintenance is active, I get about 600 or more notifications a day, and this is very annoying:
I can't take of notifications for project-changes, this would break my workflow, so we need a way to disable notifications by that account. Sadly it's not possible via herald.
