You’d think this would be obvious, but it took a recent law suit and a judge’s ruling to confirm Google, Yahoo and Microsoft don’t have an obligation to run every submitted ad.
Someone bought some gripe ads on Google, Yahoo and MSN, only to have them rejected. He then sued all three companies arguing that the search engines should be required to post his ads. The judge in the case appears to have made quick work of it, dismissing almost all of the claims and pointing out in no uncertain terms that many were specious and frivolous.
If I had a “dumb moves” category, this news would be filed there.
