This anti-racism campaign is shaming Internet trolls by putting their hateful tweets and comments on billboards in Brazil. One downside of the web is it allows people to hide behind their computer screens and say things to and about people that they probably wouldn't say in person. The Racismo Virtual, Consequencias Reais initiative from non-governmental organization Criola is addressing this problem.
The anti-racism campaign (Virtual Racism, Real Consequences in English) does not censor the identities of the individuals, likely in an effort to make them feel as humiliated as the victims of their written insults. The website for this campaign also includes maps so you can see exactly where in Brazil the offensive billboards can be found.
While the shaming technique does not address the root problem of racism, it might make people think twice about their online commentary.
