WikiTree is a horrible site. A lot of the profiles are "managed" by societies, such as the Great Migration, Puritan Project, Presidents Project, etc (not sure if I have all of the societies names correct).
My experience is that WikiTree could careless about information being accurate. And if you reach out to any of the societies who manage the profiles or at the very least, help to oversee them, expect to be ignored. It appears to be a very "clicky" platform where you are either in or out - no outsiders will be accepted or acknowledged, bit egos run this platform and if you do not agree with the folks who are "in" the club then you will find yourself out in the cold.
I would NOT recommend WikiTree, paid membership or otherwise.
