PlentyOfFish claims that MySpace is suspending all dating and diet campaigns:
Apparently they got an email saying:
I have a bit of news about your campaign. Rupert Murdoch has decided to put all dating & dieting campaigns on MySpace on hold for a few days. They are discussing about dating creatives currently and planning to come up with a set of standards for them. I wanted to notify you and let you know that the campaign will be halted today and I will keep you updated as soon as I hear some news. I apologize for the inconvenience
Dating, Diet and Mobile comprise the three biggest categories of performance based advertising on social networks, so two of the big three are affected. If this suspension continues it will likely have a measurable impact on MySpace’s revenues.
