I have received no email of complaint from you, if I had I would have responded.
Your thread was deleted because it contained at least two defamatory statements. I have been travelling, and deleted your post whilst sitting in a busy and very noisy airport - there wasn't time to send you an explanatory email, and for that I apologise.
Post deletions happen for various reasons; it's hardly the end of the world, but where potential libel is involved I will act rapidly, and sometimes - due to pressure of work - there isn't time to observe the niceties. Don't take it so personally.
