Completely forgot to update this. It's apparently to do with the EU General Data Protection Regulation (https://en.wikipedia.org/wiki/General_Data_Protection_Regulation https://en.wikipedia.org/wiki/General_Data_Protection_Regula...) due to come into force in May 2018. I'd imagine this is specifically linked to the requirement for data-controllers to be able to prove consent.
