I don’t know how it works, but this is the description
Our Free VPN (Virtual Private Network) server is designed with the latest technologies and most advanced cryptographic techniques to keep you safe on the internet from prying eyes and hackers. Our VPN securely routing all your internet traffic through an encrypted tunnel to bypass government censorship, defeat corporate surveillance and monitoring by your ISP. VPNBook strives to keep the internet a safe and free place by providing free and secure PPTP and OpenVPN service access for everyone.
Rumorhas is that VPNBook stores logs of data transferred. Not sure if there is any merit to that, but it’s something to keep an eye out for. If y’all care to know. I might give it a try, though. I’ve seen a lot of positive (if very cautious) feedback about it.
As /u/blessheimPlate said, donations and ads. Now, I didn’t notice any extra ads while browsing, so I’m assuming that it replaces some of the ads on websites with its own ads. I’m sure it’s possible. Megaupload did this in the past with Megakey.
It is. A VPN will add overhead to every single transaction. This may or may not be significant but it will not be zero.
However with that said, It’s More Complicated Than That because you’re splitting one slow link in two; one marginally slower link and one much, much faster link. Also there is the possibility of aggregating and/or compressing traffic.
Why would they bother? Facebook gather more info on us in a day than all the Federal agencies can do in a year. All they have to do is place a packet sniffer on one of the main Internet trunks near Google or Facebook and they’re set. Figures, the one time they save some money is when we don’t want them to do something.
It’s interesting that you think it being Romanian makes it solid. I would think the total opposite. A lot of computer related fraud and theft comes out of Romania.
I’m just suspicious about organizations that say ‘hey- do all of your questionable stuff over here. We promise not to tell anyone’. Mostly because if I was in the policing business that’s what I would do.
