My usual Adsense text ads (even link ads) on most of my sites are being replaced by unrelated image ads for the Wall Street Journal or Buy.com at the moment. They look like CJ javascript links, ex:
javascript:submitCJ123456789('CJ123456789',null);
It's happening everywhere, wherever the sites ares hosted, so this can't be a hack, I checked the files on my servers, they haven't changed, and Firebug tells me it is coming from the Adsense code.
Have I missed something?
