The WMF'ers have
done some analysis of the Pending Changes experiment (which, if you'll recall, was launched in response to my "
creative revisions" experiment, fostered by MZMcBride).
The ten Wikipedia articles that were placed under protection of Pending Changes that had the most anonymous edits that were, to a number, entirely unapproved were:
Ann Coulter - 39 unapproved anonymous edits
Sepp Blatter - 38 unapproved anonymous edits
Great Wall of China - 35 unapproved anonymous edits
Christopher Columbus - 34 unapproved anonymous edits
Domestic sheep - 31 unapproved anonymous edits
Telephone - 29 unapproved anonymous edits
Scientific method - 27 unapproved anonymous edits
Matt Smith (actor) - 24 unapproved anonymous edits
Turtle - 21 unapproved anonymous edits
George Washington - 21 unapproved anonymous edits
Special mention, though, should go to Nicole "Snooki" Polizzi, for her 153 unapproved anonymous edits, more than any other article... although she did have 42 anonymous edits approved, so it can't be said (like those listed above) that
every anonymous editor had something in for her.
