For my two cents worth, I think the problem is that it is not easy to find these naming guidelines on Wikitree.
Many people join Wikitree, create their profiles from GEDCOM files, dont realise there are strict rules about naming standards, and by the time they discover these rules exist, the problems have already become embedded in their profiles and they get discouraged.
I believe the FAQ sections of Wikitree need more prominence, and in particular, I dont think a newbie would be able to find the naming style guidelines for medieval and Aristo profiles unless by some kind of lucky chance, the said newbie was cruising the G2G feeds and worked out that a project existed that created them.
I would put a sentence in bold type on the Wikitree home page that says "if you are creating medieval profiles, please read these guidelines before you do". and then link to the naming standards page, rather than having these rules buried away via a link on a project page.
Sometimes I think Wikitree members forget how confusing this site (and things like naming standards) can be to the uninitiated :-)
