The UK's Financial Conduct Authority (FCA) is leading an international investigation targeting influencers who promote financial products on social media without proper authorization. This crackdown involves market regulators from six countries collaborating to address illegal financial promotions. The FCA plans to issue 650 requests to social media platforms to remove unauthorized content. The coordinated effort also includes arrests and focuses on removing hundreds of targeted posts, aiming to curb the promotion of risky financial investments across multiple jurisdictions.
