Primus Telecom's general manager of product management, development and strategy, Campbell Sallabank, says they aren't welcome back.
"No spammer is welcome back on our network," he told ZDNet Australia . "We don't single out individuals. We have a general policy".
The spam began originating from the iPrimus network almost immediately after the termination of the spammer's BigPond account last week. Queensland Computer Company have been identified as spammers since February, and have even engaged in dictionary 'attacks', where e-mail addresses are randomly guessed at by automated software.
Attempts to send mail to addresses such as adama@domain, adamb@domain, adamc@domain and so on have proven the marketing campaign is not based on opt-in e-mail addresses.
While the company has been put out of action temporarily, Sallabank concedes there's little that can be done to stop them from coming back.
"It's very difficult. All we can do is look for spikes on our outgoing mail server... if it looks like spam we can disable the account," he said.
Until new laws are passed, iPrimus will just continue to enforce its policy.
"We do that systematically anyway on our accounts... but once again it's not an easy task, and when you've got such huge mail volumes its not easy to detect an overall spike," he said.
Does anyone know the 'physical address' of the Qld spammer? If so post it here. It will be interesting to see what they think when some of there victims choose to turn up un-announced and uninvited.
