My understanding is the rule comes from some form of EU legislation, in which case the issue is far more extensive than just the UK, ~500 million people.

> It started as an EU Directive that was adopted by all EU countries in May 2011. The Directive gave individuals rights to refuse the use of cookies that reduce their online privacy. Each country then updated its own laws to comply. In the UK this meant an update to the Privacy and Electronic Communications Regulations.

Interesting... it's like when you sign up for those discount cards at stores, do I see some law somewhere that says "By the way we collect and sell your data for money which can potentially be used against you in the future to deny you health care..." I don't know... out of my field here... but. Interesting, probably worrying about nothing as usual.
Like worrying about modifying the icons of big social media sites... what blog/website doesn't create their own version/theme of those buttons...
Yeah I'm not clear on that definition of business, if your site has ads, it's meant for the Philippines, and a person in the EU visited your site, and you made money from those ads... is it my fault? Doesn't Google Adsense have to know the content of my site and the visitor to serve ads... Ahhhh
Our site is deployed in the Philippines (though does no use a .ph domain) so I wonder if the UK thing would even apply. Currently no products/associated with the site so no "business" not even ads at this time.
