Facebook, Adroll, Outbrain, XAD and Taboola were added to our website recently in order to better understand the impact of our social media marketing. Due to the concern expressed in this thread, we have removed them all from our website.
We had utilised these trackers in order to assess the impact of our social media and marketing, and to gauge the impact of our work and changes. We do still have Google Analytics installed ( with 'anonymizeIP' set to true ) to give us some basic insights into our traffic and Adwords efforts, however we are actively looking for a replacement.
We will make further announcements as they become available.
