Hi Guys,
Project protection came about a few years ago. It was started in order to protect Last Names at Birth, especially on our ancient Royal lines that we have to use dynastic associations for LNABs since they didn't have official ones. With Notables, they are protected for the same reason. We have users who do not know that some people use pseudonyms their whole life, so they try to create profiles using that, or they misspell the name, and now that protection extends to parents, which also has been an issue. Anything else can be edited by any user who has signed the Honor Code. There are just some details that are more difficult or frustrating to correct down the road, and those get protected with the PPP status. Notables also tend to be duplicated because people like to find or add their favorite famous folks, sometimes without looking to see if they exist first.The attachment of family makes our situation a bit different from Wikipedia.
