Nowadays it is easy to find public statements about the situation of freedom of expression in different democracies questioning the exercise of this right, perhaps as a result of the political tensions to which democratic states have been subjected in recent years. In this sense, Spain does not escape from these diagnoses. Both international indicators that try to measure the situation and evolution of freedom of expression in different States and academic scholars highlight the excessive criminalization of certain speeches that end up in criminal proceedings that sentence people who make offensive expressions, mainly through social networks. However, in order to reach this diagnosis it is necessary to put together all the symptoms that would lead us to that conclusion. Therefore, in this paper I analyze two main indicators that could shed more light on the state of freedom of expression in Spain and the impact that social networks have had on it. Firstly, I analyze the legislative evolution of expression offences since 1995, to evaluate the limits of certain expressions in order to reach the conclusion that, effectively, over the years the punitive scope of what cannot be expressed has been extended, thus limiting, at least in abstract, freedom of expression. Secondly, I analyze the jurisprudential evolution of all these crimes since 1995 to show that, indeed, the proliferation of sentences from 2015 to the present shows the increase in the criminalization of expressions that are made eminently through social networks such as Twitter and Facebook. To conclude, I reflect on the possibility that the latest absolutory sentence by the Constitutional Court of the singer of the band Def con Dos César Strawberry will increase the feeling that, from now on, all expression is admissible and, therefore, will increase free expression in general and, in particular, in social networks, since, it does not seem that our legislator is willing to rectify in its steps the excessive criminalization of certain offenses. I also reflect on the need to approach freedom of expression in a more empirical way and the need to evaluate not only the limitations that the law and judicial processes impose on freedom of expression, but also the extent to which citizens in general and, in particular, users of social networks, without the need to have gone through any criminal proceedings, have stopped expressing their opinions because only in this way will it be possible to determine the state of health of our right to freedom of expression.
