A global off switch that is only availalbe to "Users"
AKA, people who agreed to permanently waive broad sections of their rights away in return for gaining access to a privacy settings page that Facehugger Inc can change at will, and includes terms that the company can change at will. They can and will constantly Opt-In your account to things on a regular basis even if you don't log into the service after opting out.
Big surprise that Canada and the EU have spanked them for this. Another useful observation is how the sky hasn't fallen on either of them as a result.
Interesting question, what happens when an account created outside Canada or he EU starts posting and tagging pictures of people IN the EU?
