Nobody should trust the VPNs especially if you are entering sensitive data through the VPN.
Recently the Perfect Privacy VPN servers were seized by the dutch police without any notice and it's not the first time that vpn's servers are seized.
But using VPN for normal surfing, unlocking the content that is blocked by country or region then its ok but not submitting sensitive data.
Have to disagree. I use VPN on open networks (starbucks for example) - which is 100 times more secure. just to name one usecase other than anonymity
In this case using VPN is safer rather than using open networks like startbucks, coffee shops or airport.
But not all the time your data are safe using VPN (no matter where are you using it).
Also using bitcoin to purchase the vpn is better than paying with credit card or paypal which increases the anonymity.
