There is a 2-year old (closed) thread about wrong attribution of authorship – see blogoscoped.com/forum/138085.h ...

I did not know about it but witnessed similar problems – even articles apparently written by "O bin Laden"! This my a summary of the experience: vacilando.net/node/411418

I really do not understand why does it take such a long time for Google to fix this rather embarrassing issue!

Here's a Google search that returns an article incorrectly attributed to "O bin Laden":

[edit: fixed the URL to work around the forum doublequotes escaping bug]
