2 Click Solution

Automatic tracking of page visits by third-party social sites like Facebook, Twitter or Google+ have caused concerns about the legacy of this in accordance to the EU law, notable the collection of user information sent to the US servers without explicit user consent.
There were reports along with words of lawyers that it would be sufficient if the integrated like button would not automatically trigger an interaction with the US server per se, but only with user consent, i.e. manual interaction like the click.
Heise.de came up with a 2-click-solution that will effectively disable unintentional automatic tracking but show a dummy picture before instead and allow the user to selectively allow it for the whole site.

The PHPWCMS module includes this feature, slightly adapted.
