Dissenter acts as a workaround for people wishing to comment on websites, even those without a comment section. One user, Cody Jassman, describe the plugin as âlike the graffiti painted in the alley on every web page. You can take a look around and see what passersby are saying.â The plugin was launched in beta at the end of February by Andrew Torba, who co-founded Gab, a far-right social network. Gab is well known for being the platform where Robert Bowers, the suspected Pittsburgh synagogue shooter, published anti-Semitic comments before he allegedly killed 11 people and wounded many others at the Tree of Life synagogue.
