Posted by Thomas R. Burke Email addresses that are available on website pages remain the richest target for SPAMMers who “harvest” addresses using automated systems that easily search for the “@” symbol. In a study released this month by the FTC’s Division of Marketing Practices, the government also found that email addresses posted in chat rooms, message boards, and blogs were “far less likely to be harvested.” This may be because operators in some chat rooms automatically remove postings that contain email addresses — in contrast, website pages typically remain static. Best news: free anti-SPAM filters were highly effective in catching SPAM, although SPAM caught by ISPs remains a burden on the ISPs doing the filtering.
