Ticketing site YES24 will be taking legal actions against those who used a so-called macro system to purchase concert tickets. 

On August 24, a representative of YES24 announced, "We are preparing to sue Cho and 6 others who continuously used macro to purchase a mass amount of EXO, SHINee, and other idol group's concert tickets. Previously, we met and warned Cho, and even signed a contract [with him] stating he will never again purchase tickets this way. However, he was found using the macro system to purchase SHINee concert tickets again."
