As of this date, November 13,2021, I'm new to genealogy research with online sites. I have only paid for one subscription service [GenealogyBank] that was a disappointment. I've been using the free site FamilySearch for about six months now, finding it an interesting way to spend the time during the pandemic lockdown. Right away I found mistakes in my own family tree, that were made by people who had been careless about "attaching" records to my own grandparents. They were obviously wrong, as I could tell from my own personal knowledge. I corrected them and then took up the mission of making as much of the publicly available (free) information on my ancestors correct and comprehensive.
It soon became obvious to me that certain editors on FamilySearch were interested more in volume than in accuracy. They weren't necessarily "malicious," just careless. FamilySearch does have a way to report "malicious" actors, but most mistakes I've found don't seem to be of this category.
Another annoying feature is that people can supply "evidence" in support of their ancestors to FamilySearch that is hidden behind a paywall from a paid site like Ancestry.com. If one doesn't have a paid subscription to Ancestry.com, one can't verify or challenge the supposed "documentation."
I am looking for someone who has done research on the FamilySearch site to come up with ways to verify source accuracy.
