Esta investigación analiza el uso de Twitter por parte de diferentes fuentes informativas y políticas, durante la campaña electoral andaluza de 2018. Para su realización se creó un bot (unfaking_es) que tuiteaba informaciones relacionadas con la campaña por parte de fuentes seleccionadas previamente -partidos políticos, candidatos, medios de comunicación-. Se diferencian dos momentos en la campaña electoral que aceleran la verificación de los hechos y los discursos, los debates electorales y la jornada electoral.This research aims to analyze the use of Twitter by different news and political sources during the Andalusian election campaign of 2018. In order to do so, a specific bot (unfaking_es) was created. The bot tweeted -with a series of preconditions- information related to the campaign from selected sources. Four informative actors were distinguished: political parties, candidates, media -including factcheckers- and official sources. Our work concludes that two different moments can be distinguished in the electoral campaign, which accelerate the verification of the facts and the speeches: the electoral debates and the electoral day
