You seem to be joking but it actually is well documented.

• The 50 Cent Party, or 50 Cent Army, is the colloquial term for Internet commentators, who are hired by Chinese authorities in an attempt to manipulate public opinion to the benefit of the Chinese Communist Party. It was created during the early phases of the Internet’s rollout to the wider public in China.

The name is derived from the fact that such commentators are reportedly paid RMB¥0.50 for every post.
