The answer is .... banned advertisements.
In the case of Jerusalem, there was this earlier this month:
Britain's advertising watchdog has banned an Israeli government tourism advert for suggesting that the Old City of Jerusalem was part of Israel...The newspaper brochure showed a panorama of the walled Old City with the text "Israel has it all", and was ruled misleading by the AdvertisingStandards Authority (ASA), which said it implied the UNESCO World Heritage Site was part of Israel...Following a complaint, the ASA ruled the title of the brochure "Israel Land of Creation" and references to Old City attractions was misleading and banned the advert from appearing again in its current form...
"We understood that the status of the territories in question was the subject of much international dispute," the watchdog said. "We therefore considered the presentation of the ad would mislead consumers into believing that the Old City of Jerusalem was part of Israel and into taking a transactional decision that they would otherwise not have taken." The brochure included a photograph showing the golden Old City landmark and Muslim shrine the Dome of the Rock, with the modern buildings of Western Jerusalem in the background.
And two years ago, there was this:
A raunchy TV ad featuring ex-Baywatch star Pamela Anderson has been banned for being sexist and degrading to women. The ad, for web hosting service CrazyDomains.co.uk, featured the Barb Wire star in a boardroom full of men. While addressing the board Anderson and her assistant, Vanessa, show a lot of cleavage and one of the men fantasises about the pair dancing in bikinis while covered in cream.
Dreamscape Networks, the parent company of Crazy Domains, said the dream sequence was not "gratuitous or pornographic". Watchdog the Advertising Standards Authority received four complaints that the ad was offensive because it was sexist and degrading to women.
