Major banks have updated their privacy policies to allow for the monitoring of customers' social media profiles, posing a threat to their privacy. This has led to mounting pressure on high street banks to disclose the checks they conduct on customers, particularly after Nigel Farage had his accounts closed by Coutts due to his pro-Brexit views. The revelation has given some a further reason to consider decentralized finance (DeFi) protocols, which are built on blockchain and designed to be censorship-resistant and privacy-focused. However, as DeFi grows, it is facing increasing pressure to conform to financial norms and clamp down on money laundering.
