Recent actions by YouTube have targeted users who use VPN to purchase Premium memberships from different regions. The platform started cracking down on this practice to address users who exploit price differences between countries. Some users have received notifications demanding them to update their billing address to match their actual location in order to continue enjoying membership benefits. YouTube's official response includes establishing a system to verify users' actual country or region and require them to update billing addresses accordingly, although specific areas being targeted were not disclosed.
