In one of the dirtiest electoral campaigns in Brazil's history, figures on the left and right of the political spectrum trolled their opponents with jokes, ridicule and disinformation rocking the country's young democracy.

We speak to both sides including a Congressman whose series of ambiguous or misleading posts on Twitter got millions of views and an Argentine political consultant whose false claims about voter fraud went viral, playing a key role in the movement that led to widespread national protests.

So how has trolling evolved to become a central feature in Brazil’s political discourse and is there any way back from here? Jonathan Griffin and Juliana Gragnani investigate.
