Scientists have carried out research on false profiles, or ‘fakes’, of famous people on the social network Twitter and the use of language on them. The study tries to answer questions like whether the misappropriation of the identities of famous people is normal practice on Twitter, in what cases it is permitted, what effects the parody can have on the image of the celebrity and the social role of someone who is well known and to what extent the messages published by fake accounts can be seen as examples of bad manners or even verbal violence.
