In regards to using a VPN for privacy: The important thing about a shared VPN service is that it makes it difficult to distinguish traffic, and by sharing multiple IPs across different countries it becomes even harder to track an individual's activities. This is somewhat of a copy of Tor, but with less security-risk, at the expense of some privacy. Whereas if you run your own VPN, for example, all activity from that IP address gradually becomes more associated with you.
