Locating the changes made by a specific user
I sometimes encounter issues in the tree that were caused by a single user and affected hundreds of individuals that I am not related to. These are usually problems such as over-merging, which takes up most up my research time to correct. There is one user known to have Alzheimer's, and I have carefully been undoing all of his mistakes I can locate.
I recently ran into an issue where someone deleted individuals rather than merging them, stating that they were "Tired of all Familysearch problems". In cases where they couldn't delete an individual, they replaced vital information with "x" or "xxxx". Unfortunately, this can cause their identity to be altered, as can be seen in the changelog of this individual: L5PK-P7K. I would like to be able to locate all of the individuals that got this treatment and correct the error before it causes further confusion. This capability may be reserved to admins, but is there a way to track down all of the changes made by a specific person?
I've just been searching through changelogs, but I worry that I might miss someone and they won't be restored. I can also use the Find person feature and search for "x", but I would still miss deleted individuals and I can't narrow it down in the ways that are most helpful.
Thanks in advance!
