One cause for this to happen so often is related to the hard time people have finding these profiles. For the Dutch Royal Family, it took me over half an hour to find the profiles. Not that I wanted to start one, but it was really strange not to find them 'at once' as they are the ones looked for a lot.
In my opinion this has to do with the strict search on LNAB, and not on the commonly used names. A smarter search, including nick names, would really help in this respect.
