"Shane has a policy of denying written references to its employees in order to make sure that this kind of information does not proliferate and hinder their recruitment process as this undoubtedly will do, not that this was my intent."

This is completely untrue. Shane does give references. What "sparrow" may be referring to is the fact that Shane does not issue "letters of recommendation" (open references). And why would Shane commenting on a teacher promote the proliferation of anti-Shane information? You do realise that when writing a reference, it's the school that er..writes it?
