Peter Shinbach recently threw in the towel and shut down Bach Door, his online-communications blog. The public relations executive from Birmingham, Michigan, was fed up with so-called comment spam. Returning from a weeklong vacation, he found a slew of comments on his blog that had nothing to do with communications: They were posts from spammers promoting gambling sites and prescription drugs. Shinbach is one of many who are starting to fret more about <A HREF="http://news.yahoo.com/s/pcworld/20060227/tc_pcworld/124822">spam on blogs, instant messages, and cell phones</A> than about traditional unsolicited email--at least in part because old-style spam appears to be losing some momentum. In contrast, other forms of spam--prompted by the rise of new messaging media--are just gathering steam. Comment spam is one of the new forms. Another is the splog--short for spam blog, a blog that is created purely for marketing purposes.
