Le tribunal d’Internet : réseaux sociaux, culture de l’annulation et discours de haine

The contribution aims to reflect on some specificities of the sanctioning methods on social networks, transformed in today’s post-truth regime into real courts of summary justice. In particular, four aspects will be taken into consideration: i) the lack of an institutional dimension; ii) the punctual and extemporaneous character on the temporal level; iii) the absence of a probative logic on the argumentative level; iv) the strongly phatic characterization. Particularly important will be the reflection on the actantial role of the sender and on the recourse to assumption of a communicative community of destination.
