Footage has emerged of a giant "click farm" that uses more than 10,000 mobile phones to give product ratings and pages on social media websites phoney "likes".

Companies reportedly pay thousands to get their apps more likes by using services like this massive plant offers.

This covert clip in China shows rows and rows of like-making machines all wired to other devices in a factory.

And there are said to be thousands more phones in the same building all made for the same purpose.

The footage also shows a number of workers busy on computers.

Experts say digital manipulation is carried out in Russia and China but their influence is felt worldwide.

But social media users reacted angrily to this clip.

One viewer wrote: "Is everything in the modern world 'fake'?"

Another posted: "Make it illegal and set up sting operations. You could collect billions of dollars in fines every year from big companies."

While, a third furious user shared: "Is anything actually real anymore?"
