For nearly a couple months, I've been working (off and on) on my GEDCompare Report. I've also dabbled in a lot of other areas on WikiTree.
I have to say, especially after working with some adopted profiles and engaging in several Data Doctors tasks, I greatly appreciate the length and tedium of the process for "just" adding our GEDCOM from elsewhere to WikiTree: i.e., we cannot do that! By design!
Once you've edited dozens of profiles that are "less than desirable" Gedcom additions never cleaned up or managed by their originator, you better understand the Why of our Gedcom stance.
Once you've sourced a profile lacking real sources, and replaced 1-20 blocks of prior "sources" in that profile that essentially point to zero sources, you better understand ...
Once you've cleaned up a prior merge that wasn't attended to at the time of merging, you better understand ...
Once you've unsorted someone else's complicated web of an orphaned family with people having multiple spouses of very similar names but significantly different birth years and a bunch of half siblings with birth year range spans of 103 years, you better understand ...
I could go on ... but you likely already understand!
Even with the existing GEDCompare process, lacking profiles get through and will continue to get through no matter what we do. That's okay. It needs to be okay. This is a Wiki after all.
So, what's my suggestion? In addition to needing to first compare all of our Gedcom people with WikiTree profiles and, second, optionally add/edit, one by one, our Gedcom people to WikiTree could we add a requirement that the 'add/edit' process not be possible until some kind of track record exists for the Wiki Genealogist? I probably lean too strict on what the parameters "should" be for this ... so it's likely better others figure this out ... I'd do something like {1 month since account confirmation & 1,000 contributions & 600 G2G points}.
