Hundreds of social media posts and websites operated by financial influencers are to be taken down following action by the City regulator.
The Financial Conduct Authority (FCA) said the move was part of an international crackdown, which has led to three arrests in the UK.
So-called finfluencers can legitimately give financial tips on social media to large audiences, but sometimes this can stray into illegal financial advice.
That can include a lack of authorisation and a failure to explain the risks - all packaged in promotional posts using the pretence of a lavish lifestyle.
