That is what I took from the link as well. It is OK to get hold of the data. However, it is a crime e.g.: to use it to personally identify someone, or to distribute it (even accidentally! (you have obligations under the data protection act to prevent this)) (this would probably also cover using torrents to download it). So in the UK be careful and anonomise it before working with it -- as is required with e.g. similar (legally obtained) datasets in the social sciences. Then totally delete the raw dataset from your system -- otherwise if you e.g. lose your laptop you become liable for any further re-distribution. Not planning on looking at it anyway.
