The Korean Tour suspended Bio Kim earlier this week for making an obscene gesture aimed at a fan during the final round of the DGB Financial Group Volvik Daegu Gyeongbuk Open.
The decision to ban the South Korean for three years has caused a massive backlash, with many suggesting the punishment was too severe.
Kevin Na was one of those who believed the sentence handed out to Kim was harsh, saying that the three-year ban was ‘ridiculous’.
