The safety of Hola Unblocker (Hola VPN) is somewhat of a contentious issue due to its peer-to-peer model. This means your connection could be routed through other users' devices, potentially exposing your data to risks. Similarly, when you're not using the VPN, your device can be used as an exit node for other Hola users, which could associate your IP address with their online activities. While Hola does offer encryption for its Plus users, the peer-to-peer model still presents significant security and privacy concerns that aren't typically associated with traditional VPN services.
