When a luxury brand bursts: Modelling the social media viral effects of negative stereotypes adoption leading to brand hate.

In early 2020, the World Health Organization (WHO) developed the term "infodemic" to describe the velocity at which data can be exchanged among people, in a free virtual space where firms have limited control over the information diffusion. In particular, the diffusion of information on social media has analogies with the transmission (contagion) of social phenomena and infectious diseases. The aim of this research is to model the viral effects of a luxury marketing campaign when adopting negative stereotypes to increase the market share in a growing market. The campaign generated 506,127 likes of celebrity endorsers/influencers and 17,984 comments spread worldwide in a relatively short period, producing a "burst". Findings revealed the unexpected social burst occurred with negative consumers' evaluation, which has been amplified becoming dramatically damaging for the brand (brand hate).
