Since November 2016, netizen 'A' has made posts on social media with the hashtag #YoonKyeSangTaxEvasion and even shared photos of having a one-man demonstration against Yoon Kye Sang at Gwanghwamun.

Saram Entertainment claimed the netizen started sharing more of the false accusations as Yoon Kye Sang's popularity increased with the success of the film 'The Outlaws'.

Currently, the case is being investigated by Mapo Police Department in Seoul.
