You got a comment on your blog that I agree with. You could make a linkshell with more mentors that don't want to deal with the person and invite new players to it. This has been done before according to a post I read and was successful, so it's not a far fetched idea that newbyes would want to join.
You got me curious though, what exactly happened? Is it allowed on forums to post pics with names blurred out? How do we know it isn't you guys being strange if even the GM isn't approving?
