Ivpn: canary, audited, anonymous accounts purchasable with crypto or cash, no performance issues, no logs (allegedly), open source protocols and clients.
I really like their blatant honesty in "Do you really need a VPN?"
Fundamentally, the only use case of a VPN is if you trust them with your traffic more than your ISP. Since I've had multiple ISPs that serve up adds instead of 404s and will threaten you for using p2p protocols it's easy to trust a VPN more. As best I can tell Ivpn is just a couple of security peeps running a VPN service cause they can--could they be corrupted or a honey pot? Yeah, but the anonymous accounts help mitigate that risk, and the reality is that even an anonymous account can be tied back to your IP. So don't do anything illegal illegal on just a VPN and it'll prolly be fine.
And they're not advertised through everyone with a platform.
