If your kids use Twitter, you might have heard about how the platform has been suspending the accounts of users it believes were underage when they signed up for the popular social media service. This move has caused widespread confusion and raised questions for other companies struggling to comply with new data-privacy laws. While it is not certain what has prompted this action, media reports highlight examples of account suspensions that occurred in late May when the European Union's new General Data Protection Regulation, or GDPR, came into effect. That new provision holds that tech companies processing the personal data of children must obtain explicit consent from a parent or guardian.
