Thank you for your interest in the WikiTree project and for your comments here.
The ongoing problem of duplicates on the WikiTree is one that the sysops, supervisors and arborists work on every day, and the profile you point out is no exception. All profiles here are works-in-process. Pruning the duplicates is a job that will continue far into the future.
Why? Because WikiTree is a place where people can share their existing work and knowledge (including flawed work and unsourced entries) as that is the way it must be in order to function as a true Wiki effort - as a truly collaborative world-wide family tree.
Douglas-391, the referrenced profile, needs some pruning and this will be done. In the mean-time a new member of WikiTree may come along, and with all good intentions, upload another GEDCOM containing not only William, but all of those connected to him: parents, siblings, spouses, children. Though the process is managed to reduce these incidents, they cannot be entirely avoided without implementing far more rigorous (meaning = harsh or demanding) controls than a Wiki effort would want to contain.
Thus, while your concern is legitimate and appreciated, the solution to the problem is, (and for the forseeable future will continue to be) more volunteer help, particularly in the Arborist role. Please contact Phillip Smith at the Arborist Project should you feel you could help that effort.
I hope this helps,
Keith
