RomulusNR writes "Yahoo has stopped delivering This Is True, Randy Cassingham's 14-year-old mailing list, because too many Yahoo readers have mistakenly or carelessly flagged it as spam. Yahoo readers make up over 10% of True's readership, slashing the ad revenue that keeps it going. And Yahoo doesn't negotiate with spammers. As Randy describes it: 'The yahoos... ask to be put on True's distribution, then confirm that request, and... then click the "This is Spam" button when they don't recognize the mailing or simply don't want it anymore. Yes, those yahoos have screwed thousands upon thousands of others who really do want my newsletter. Too bad: Yahoo is listening to the yahoos instead: they're blocking it. To them, we're "spammers" and no protestations from "spammers" count.' The irony is that This is True is one of the first profitable mailing lists, predating Yahoo! Mail by almost three years."
