[Hola VPN Blocked on CMU](https://www.cmu.edu/iso/news/2021/hola-vpn-block.html) Network for spiking up with malicious traffic. According to them it does not use encryption and sells your connection usage to others, which defeats the purpose of VPN. Bandwidths are sold to company called Luminati (from quick search they changed name to BrightData). Users who continue to use Hola will be blocked from network, so i think they are taking this situation seriously.
Its a first time im seeing a academic community do something like this. Are any other malicious VPNs like this?
