As a general rule I don't think you should be leaving reviews of any company you're not a customer of. It's a shitty thing to do IMO.
Although not a customer, we all know what an awful job that first letter that was sent out was. Novosel has instantly given himself a bad name. Doesn't return phone calls. Negotiates in bad faith. Doesn't return email inquiries. Shall I go on?
You and I are just going to have to disagree on this one. Also by your standard, then none of us should be criticizing Lloyd as we are not customers of his books or shirts.
