So what should I do, if I come across two profiles that are obviously supposed to be the same person but have major discrepancies?
If I propose a merge, somebody else can make it an unmerged match, but more likely somebody else will just reject it. What then?
Don't tell me I should work on it myself. It's of no interest to me, I don't have access to the relevant resources, I only noticed it in passing. Perhaps I just spotted them in the "Find" output while searching for somebody else. I'm trying to do something else and the job will never get done if I chase every loose end.
But there's another reason not to work on it. That's because, if I figure out how to complete it, and propose a merge, I'll then have no control over how it gets completed. Quite likely somebody else will just accept the system defaults. Then I'll think I wasted my time.
If I want to work on merges, I'm better off picking something off the Pending list that's already got default approvals in spite of conflicts. Then, if I can figure out how to complete it, I can at least go ahead and do it.
And please don't mention PMs. If they were going to do it, they'd have done it.
What I do find is that WikiTree is training me to ignore things that need attention. Anything that's not immediately important, turning a blind eye and not getting involved generally seems to be a wiser policy. I've caused myself too much trouble by looking at stuff I had no need to look at.
