The latest scandal over fake advertising on social media comes as a major advertiser is under fire for using the phrase “honest to goodness” on a campaign that included a cartoon depicting two men who were apparently murdered in the Congo.

Dafo is the world’s biggest mobile advertising agency, which sells more than $6bn (£4.5bn) of advertising each year.

In March, the ad agency, owned by Chinese tycoon Li Ka-shing, said it would stop using the term, and the adverts appeared on mobile devices in the United States, the UK, Canada and Germany.

“I am appalled by this, and I will not tolerate such actions,” Dafo said in a statement at the time.

Dacar, which had previously said it was removing the campaign, said in an online statement: “This is a blatant disregard for Dafos ethics and standards of ethics.”

“I do not approve of such behavior, which has been documented by numerous independent experts,” it said.

But a spokesperson for Dacar said the ad was not endorsed by Dafon, and did not have the support of its marketing team.

Daclaf also has a history of making controversial adverts.

In 2014, for example, the firm made a controversial advertisement, which was also labelled as “anti-Semitism”, using the image of a Jewish soldier standing with a gun.

The company also has its own “social justice” label, which says it believes “the system is rigged” and is “not an institution that can be fixed.”

The campaign, which featured a cartoon of a white soldier, was meant to highlight Daclaf’s social justice credentials.

“We’re not anti-Semitic.

We’re not an organisation that can’t be fixed,” Daclas spokesperson, Alain de Saint-Laurent, told CNN.

But he said the campaign was still in its early stages.

“There’s a lot of work to be done,” he said.

“It’s not clear what is going to happen.”

Daclas adverts have been the target of controversy before, and last year it was revealed that some of its adverts had been edited to include a cartoon showing a man being stabbed in the back with a knife.

The campaign featured in the BBC’s documentary “Bloody Sunday”.

The advert was removed after BBC viewers pointed out that it showed a different angle of the man’s bloodied back, and suggested the image could be a hoax.
