Spammers have adapted and spam is going to get worse

In the next few months, E-mail spam is going to get a lot worse, at least, that’s the prediction of The SpamHaus project, a global anti-spam group that point the finger to a new spamming technique that consist of sending spam via the ISPs (Internet Service Providers) directly, instead of using individual machines.

It makes it impossible to block E-mails coming from the ISP’s internet address without also blocking millions of legitimate E-mails.

And that comes right after AOL claimed that spam was going down and that everybody was saying that spammers had given up… It seems that spammers have adapted. How can they use the ISP’s infrastructure and why can’t the ISPs prevent them from doing it?
