At the time of writing this report the access attempts reported by the system is over 34 million1.

There has been a noticeable increase since the similar period last year.

Since the last report 46 appeals have been received from users who were attempting to access a blocked url, this in an increase of 10 on the same period in the previous year. In all instances the appeals were processed by the review team and found to contain child abuse material thus the site remained on the list.

Below are examples of the text that was contained in some of the appeals

  • would love your job you get to perv and get paid for it
  • to view
  • Just for fun.
  • Why not
  • I will not act on it

1 This number is not related to unique users or unique requests, rather the total amount of requests filtered during the particular period. For example 1 user could be responsible for a large number of filtered requests in 1 day and accessing a gallery page with links to multiple blocked sites will result in several filtered requests being recorded. Additionally this number also includes requests as a result of website pop-ups, pop-unders and spam content that a user may not be aware of.

This quarter we compared statistical data of the period January 2012 – May 3 2012 and January 2013 - May 2013 and noticed a dramatic increase in mobile device use, this includes tablet device.
