Mass email sent.

The complainant, in his capacity as a student of the UAB, received an informative email from the International Day of the Workers' Women. By not wanting to receive any more emails of this type, he responded to the university's email, so his message was received by third parties outside his sender. This is attributable to their actions, and not to a human error or computer error by the reported entity that has led to a violation of the data protection rules, which is why the complaint is filed.
