In Indonesia, there is anti hoax legal system.
However, there are plenty of loopholes.
For example, Bob cannot say publicly a lie. However, Bob can lie to Cindy that are profited by the lie and do not really care whether the statement is true or not. Cindy can lie publicly. So technically no body "lies" to public.
In one case, Ratna Sarumpaet told a lie that she is beaten up to Prabowo. Prabowo then repeated the lie. Neither can be charged (I am not sure, the case is still proceeding).
There are phrases like know or "should have known". That is open to a lot of interpretation.
Most people understand that any info that is "false" is a crime. However, I have no idea if the laws really work that way.
Here, deliberately spreading hoax is criminalized. However, it's not clear whether a person need to deliberately spread hoax, or deliberately spreading something, that happens to be hoax. Need to ask in stackexchange.
In case of Ahok, he is charged for deliberately speaking something that are hostile to religious sentiment. Here, the judge interprets deliberately to cover only "speaking". Of course, every body speak deliberately without knowing what he said offend any religious sentiment or not.
This is a case where Prabowo spread hoaxes by saying that Ratna was beaten up. However, Ratna wasn't beaten up by anyone.
Latter, this same Prabowo said that a demonstration demanding Ahok's fall is done by 11 million. CNN says there are only 80k people.

Prabowo also said that 1% of Indonesian control 40% of the wealth by saying that's what .40 GINI index is. That's clearly false information.
However, that guy is not convicted.
I guess you get to ask someone in laws to understand why.
