The anecdote is that someone inserted a "Wilhelm" into finance minister Karl Theodor Maria Nikolaus Johann Jacob Philipp Franz Joseph Sylvester Freiherr von und zu Guttenberg's name. I think K. T. M. N. J. J. "Phil" F. J. S. F. von und zu Guttenberg has a sense of humor about it by now. Similar (though less amusing) anecdotes have been breathlessly reported for years now.
The assertions: first, that the greater part of all edits made by newcomers to the site are reverted by a new breed of xenophobic editors. This is an extraordinary claim. It's easy to disprove; go pull up Special:NewPages and watch dozens of new users create superfluous new pages every hour, most of which won't get reverted.
The second assertion, that attrition is taking a toll on WP administrators, is even more laughable. Go pull up Wikipedia:Requests_for_adminship. Status-obsessed WP dorks spend weeks and months doing menial work (like patrolling new pages) to build a case for adminship. If anything, WP's problem is that it has too many of them.
