Can you supply some authorative info to support your claim that
"she is an idiot though..."

by repeating /citing other defaming info is not authorative info mate
and IMO you are adding yourself to the risk of defamation in addition
to the OP's thread head author/publisher

IMO, it is possible that Ms Harris may be already aware of this thread
and its potentially defamatory content.

All IMO only and posters concerned ought to consult a legal expert
if in doubt.
