Not really related to the written topic of this page, but I noticed there is a sideways red button with "Leave this site" that redirects you to 'https://www.google.co.uk/'. What could be the incentive behind this? Why not just close the tab?

If you are about to be watched by an abusive person, it may be better to immediately switch the browser to an innocent page rather than possibly closing it down which may look more suspicious.
