Because there are only <500,000 LLLL.coms in existence and they are a hot commodity in the Chinese market right now. If you have any 4L.com at all, then you are more than likely to get these emails as they probably just send them to everybody with an LLLL.com. I believe there is real intent to buy but when email blasting at first they don't consider the individual name or quality at that point. Also if/when a deal is potentially reached there are the issues of making payment internationally along with language barriers, etc.. which can all make it more difficult to close.
