As Pip said, I too added many sources for the profiles I worked on and I didn't get credit for most of them. It's still a better idea than plopping something down that the PM may not even look at. Consider this, if the profile has a PM and it's unsourced, they probably aren't all that interested in getting it right.
My biggest issue this year was all of the poorly "dropped" profiles, whether GEDcoms or adds without any dates or places. Sourcing those is ridiculous. How do we stop people using ancestry.com as a source, or just listing census years without the information and no links? I have had communication with wikitreers who believe ancestry.com is a perfectly acceptable source. It's NOT! It's one thing if they actually put all the information and a link, so at least people with an account can verify it. But, linking to an account where all the "sources" are other trees, or not including a link at all? NOPE!
Another thing I saw this year was a series of profiles of one family and its' members added with * as the only source! That was done by someone who knew how to game the system in order to add more profiles.
There must be some way to do a better job of vetting new profile creation and teaching new members how to use Root Search before they're made full members. I didn't understand Root Search, or how to use it, nor did I know about FS until I started on Wikitree. Maybe there could be a requirement that new members, given some basic names, dates, and places need to create a "Fake" profile with at least one source from FS using Root-Search?
Wikitree has a high learning curve and maybe some of our leaders have forgotten that? More robust requirements for adding profiles has to occur sooner rather than later, or our tree will end up with the same kind of messes I see on FS and Ancestry -actually, it already has.
I don't write code, I don't know how to program, and God knows I don't want to make more work for our leadership, but if we don't fix these issues now, they will continue to create more work for the dedicated members of our tree who work here almost daily.
