I own a MediaWiki website that is showing Google AdSense. As of September 30th 2015 AdSense requires compliance with the EU cookie law.
The Google Adsense Team is pointing to https://www.google.com/about/company/user-consent-policy-help.html and it looks as if Adsense will be disabled on websites that don't follow this page and https://www.cookiechoices.org/.
I'm open to creating a MediaWiki extension, but I'm not sure what would be a good starting point. Maybe cookieguard, a jQuery plugin? Any other ideas?
