The way I'm looking at this project, won't it be illegal in some countries to visit the site, I just want to know if I need to use VPN just to protect myself from any possible legal issue
You should use a VPN everytime you log your computer on. Why would anyone want to be tracked online and kill the little privacy we have left. I don't do nothing illegal but always use VP because I don't like the fact ISP's know everything I may or may not do online.

ALWAYS use a vpn for everything you do on the internet!
What kind of VPN are you guys talking about? How you can use VPN to connect to anything? VPN (be it ipsec, pptp, openvpn or any other kind of it) is a peer to peer protocol, where both sides have to know the keys, so you can VPN to your workplace network, or some other private network, but as far as I understand you cannot use VPN to connect to random sites? So I wonder what I miss here?
