TDE is the most prestigious spammer on the Abusive Hosts Blocking List (AHBL), which is used by American ISPs to identify the worst spammers in the world and block them.
According to the AHBL TDE users are flooding the world with thousands of junk advertising emails and dodgy financial scams.
It is rare for a whole ISP to be blocked, but AHBL said that TDE seemed to have a complete indifference to the amount of spam that was coming out of its servers.
The watchdog woofed that TDE had failed to bring in the most basic of anti-spam measures including blocking email that comes straight from a user's computer instead of through the ISP's server.
According to a statement on the AHBL website: "The only reason why we have resorted to this broad of a block is because TDE has not shown any effort to work with us to isolate the problem, and we continue to receive thousands of spam attempts daily."
TDE has said that most of the spam comes from internet caffs signed up to the state-run company. The company has more than 50 million users. µ
