This because a new European Data Privacy Law called General Data Protection Regulation (GDPR) became law on Friday 25 May 2018 here in Europe. Theres a whole load of new data rules, and this banner is one of them. The law states that any website which uses cookies for things such as Google Analytics, Google AdSense and a whole load more ways must inform users. The website must also have a privacy policy which gives inform on what cookies are used, what data is collected, why the data is collected, how long the data will be retained, where the data is stored and who has access to the data. It also gives website users the right to request the data that has been collected about them and for this data to be removed and deleted.
As this is a legal requirement, this Dis have to have this banner on the website. To remove it, you just need to click on Got It : )
