Since I am on the SA Roots project, I see suggestions for matches, which when made by my fellow genealogists, are generally well motivated, but even so not always to be supported.
Today there was a merge suggested by something called MatchBot. This looks like the same piece of software that suggests dozens of totally irrelevant names when one creates a new profile.
In this case, it seems to have jumped to a conclusion that two persons with the very rare surname Smith born on the same very precise date ABT 1870, whose profiles do no contain any actual contradictions (except that one "died young" in prose and the other lived to 66), are worthy candidates for a merge.
Its counterparts at MyHeritage, Geni etc are responsible for most of the halfbaked if not totally raw profiles that get GEDCOM-imported into WIkiTree.
WikiTree leadership: if you want to chase me off WikiTree, you've found the way to do it. Up to now I have seen WikiTree as a place where I can publish my family search subject to peer scrutiny, and I would like it to stay that way.
I can understand that there are people who enjoy the challenge of writing this kind of software, but I conservatively estimate that another five years of intensive development will elapse before anything useful comes out of it.
In the meanwhile, can those suggested merges please be only sent to those who work on MatchBot?
