Okawa Zeng spams

The page lists 12 spams received from the persistent spammer (according to the headers) okawa.zeng@msa.hinet.net. They all appear to have been sent to many thousands of addresses at once. They claim to have originated at hinet.net, which appears, based on other evidence, to be a spam support provider. (For example, I have received numerous spams with the email address chen-a999@umail.hinet.net in the text. After every one, I have asked that the address be cancelled. Since spams for the address kept coming, I can only conclude that the address continued to exist.)
