LMAO, me too!!! These guys come from all over the place! They don't know how to fill out a form either, I'm in the process of tweaking the form, and these guys expect to get a reply when they only fill out half of it. They don't even add their email address or website name.
I'm not sure where they got my address from, but I have gotten visitors from that website you posted, and tons of other chinese web forums. I remember a while back I was working for this company, and I went to one of the URL's they came from, and they had actually taken the whole form from the company site and added it to theirs so people can signup without even visiting the company site! These people are on 24/7 alert for free hosting. I really don't mind giving free hosting, but when I get tons of signups half filled out, it gets annoying.
