Some guy named Caleb Howe contacted Facebook about their temporary pulling of ads for NoStimulus.com. Their answer:
As part of our efforts to remove other ads with misleading offers related to the stimulus package, we erroneously removed the ad in question. We have since restored that ad and expressed our regret to the advertiser for the error. We apologize for any inconvenience this may have caused. Part of Facebook’s mission is to give people the power to share their opinions, and we encourage users to start vibrant debates on important issues. Already with the stimulus package, we have seen users create Facebook Groups and lead discussions on all sides of the issue.
That’s a lot of words not to say anything? What efforts? And how did the error happen? My guess: They saw a bunch of scams, and some lazy staffer blocked too many ads, just going through the motions of his job without paying enough attention to what he was doing.
