How to ban fake news?

Fake news has been a big problem for all countries for such a long time, but has Malaysia found a way to stop it? Although Malaysia does not have a huge problem with fake news, "Malaysia has passed a law criminalizing it, with a penalty of up to six years in jail" (Head, 2018). Any information run by the government and not verified by the Malaysian government is considered "fake news." Only problem I see with this is that if the government doesn't want something to get out to the people, they can claim it to be fake. Hmm I don't know about that..
