Finding inputs / changes by username
I am raising this issue "again" as unfortunately the thread / similar idea under the General Questions category has now been closed.
It has been suggested that an ability to search for records added / changed by a particular user might infringe privacy rights, although I don't quite see that: we still would not know the identity of that individual - only an administrator could establish that.
I feel the discussion at https://community.familysearch.org/en/discussion/comment/530159#Comment_530159 shows how useful it would be to be able to trace certain inputs that FamilySearch policies do not regard as "abuse", or for which there is the will or the ability to assign sufficient resources to deal with such matters.
As illustrated by @LFarrier, there are certain users who are consistently causing damage to the tree through their inputs. When I come across some examples during my daily work in Family Tree, I can obviously clearly see the username attached to such work. However, I often wonder what I am missing - i.e., what other damaging work are they doing elsewhere in the tree, even to branches that include my own relatives. (Naturally, I can't keep a regular eye on them all - via my Following list, or otherwise.)
I know my argument is partly flawed by the fact (as illustrated in the other thread) that a user can adopt multiple usernames (I have previously expressed a wish for this to be more tightly controlled, too), but I really wish there could be an easier way to locate the work of "serial offenders". If FamilySearch would be willing to get more involved here I would not feel such a need to monitor the work of these individuals - some of whom have be proved to even have serious mental health problems, so not meaning to be too harsh on them personally, in relation to their damaging activity in Family Tree.
I am happy to acknowledge (as above) the flaws of a "Search by username" option - perhaps a vindictive user could deliberately target the genuinely correct inputs added by another user, just because they had had a disagreement on one issue. So, I guess I am desperately looking for any better ways of stopping this tiny minority of users from wreaking havoc with our Family Tree.
