The technique allows spammers to include a link in the email constructed from a search engine query. Eliminating the URL in the body of the email message makes it difficult for anti-spam applications to detect. Plus, the link leads the person to the spammer’s Web site.
Search engine spam was down 1.3% and email spam by 0.06% in February, but it is expected to pick back up as the recession continues.
I would think people would be more aware of email spam by now, but with every chain letter forwarded from my aunts, I lose hope.
