News Corporation's Myspace may be, as its tagline goes, a place for friends. But the social network's execs fight nasty when riled. Founder Tom Anderson, in his latest notice on the site, threatens the "losers" behind the explosion of comment spam. "Good news is we won some recent cases which is going to make it easy to punish the beejesus out of them." The ultimate punishment? Ask Joseph Tierney, a spammer who created thousands of fake Myspace accounts in order to clog users' pages with lame marketing links, and then offered his technique to other spammers. Tierney, creator of the Spacepromoter software, said Myspace's lawyers have demanded he give up his domain, and promise not to discuss Myspace marketing. The worst of it: he must never visit the site again.
