Originally reported by @Ramsey-WMF , there were about 125 tasks affected on Structured-Data-Backlog by @Sarahmarie1981 . Approximately 25 have been reverted (thanks @Aklapper !), so about 100 remain. I'm not aware of a way to search or filter by user-has-edited, so that may have to happen on the backend.
Happy to help with this if Phab provides a tool to help me identify more automatically than searching each task. We know the tasks exist because of email notifications, but it's not easy to quickly make a query from that. :-/
