I really think our friend from China has missed the point of a blacklist. It is not to determine whether or not a business is legitimate or a scam (although it may include this) and certainly not a racial or ethnic indicator of reliability. It indicates that they are sending out unwanted emails. Whether we are talking a personal or business email account, a site that has been blacklisted is sending out emails that were not asked for or wanted by users. I, like many others who use spam programs, are just tired of downloading countless messages that are sent out in bulk. If a company wants to sell a product, get a website and stop using peoples emails. I have to ask our Chinese friend...What gives you the right to send me an unsolicited email that along with a thousand other companies like yours, just fill up my inbox and waste my time downloading them? Spam programs using blacklists are doing it because WE the customer have asked for it. A lesson our Chinese friend might want to listen to if he is conducting a legitimate business.
