One of the actually very positive aspects of COPPA was that one section of it said parents had the right to contact companies and find out all the data that a company had collected on their child and to put in a request for the data to be destroyed. According to people who have followed up and studied how the act has functioned and not functioned over the past 10 or 12 years, apparently that was not something enacted very often. But that was one way. Presumably kids could also demand the same thing and find out what data had been collected on them and have some sort of recourse, an established solution, so that if they wanted the data to be destroyed, it could be.
