On May 20, 2014, Gogolook was mentioned by name during the President of Taiwan, Ma Ying-jeou's national address marking his 6th year in office. Gogolook was referred to as an example of the  creativity and potential of the youth of Taiwan. In April 2014, concerns regarding Whoscall’s privacy issues rose to the forefront of national attention as public figures took to the press and expressed their public records including home telephone numbers and addresses showing up on incoming calling screens. Gogolook swiftly came out with a statement declaring that they had never collected nor stored any personal information on their servers, let alone made them publicly available. It was soon discovered that the personal information of the aforementioned public figures was leaked from government servers with poor security protocols that made the  information available on search engines, from where Gogolook sources some of their information. Whoscall was promptly lauded as not only a call screen for telemarketers, but also a reliable reminder for the possible dissemination of personal information.
