Digital platforms can be fertile ground for the spread of disinformation campaigns, either coordinated or spontaneous, which aim to influence voting through false, manipulated or decontextualised news. The use of profiling techniques can lead to a fragmentation of public debate in echo chambers, in which voters are exposed only to information that confirms their existing views, reducing critical dialogue and polarising debate. The lack of transparency in algorithmic decision-making processes makes it difficult for supervisory authorities, observers and the general public to understand the logic behind content distribution, which risks creating invisible but significant imbalances in access to political information. Content moderation, if managed on the basis of opaque or overly automated processes, can also result in the arbitrary removal of legitimate speech or, conversely, excessive tolerance of content that violates international standards, including those against hate speech.
