You're mixing apples and oranges: historical scholarship is not required for Wikipedia to add information, say, on a claim to the Bosnian throne. (Sorry no one has claimed the Croatia's yet). To add that information to the list of many other claimants around the world does not require approval from the pope, but it does reqire that the claimant has (A) in fact made the claim, and that (B) news sources reported on it that are considered respectable in that country.  Since the news source we're talking about here are online, Alexa is the criterion for their as any other online ranking of news portals because their high position in Alexa means high readership. In the news business, this is how you measure success. The sources that reported on the claim are not tabloids but conventional news portals, as anyone can see: www.source.ba, www.bljesak.info, etc. Please be respectful, others have brains and eyes too and stop the edit war.   
Thanks for the diagram. If you look at it closely, you'll realize you're not even attempting to compromise, meaning you're the one not following WP:EDITCONSENSUS. Instead, you keep making total reverts canceling entire edits (which took hours of someone's valuable time) without ever discussing it in Talk. By being so obviously rude, you also remove dozens of reliable references such as in Ban Borić article where your remove all history ebooks from the Google Scanning project with a single hit of a button. Never heard of a rule saying that Google Scanning project is bogus and banned from Wikipedia. That's malicious editing, plain and simple. Please stop edit war. Or to use your Catholic vocabulary - please stop the crusade.
