Zico is named the member who is the most sensitive to netizen comments. 

On January 9, the Block B members B-Bomb, U-kwon, Taeil, and P.O. guested on MBC FM4U's 'Dreaming Radio' in support of the special DJ Park Kyung. 

During the radio show, one question asked, "Which Block B member is the most sensitive about (netizen) comments?" B-Bomb and U-Kwon named Zico, while Taeil picked Park Kyung. 

U-Kwon explained, "I saw Zico searching up his name multiple times. He probably reads this too if it makes the headlines." Taeil also said, "I don't talk about him because when I say Zico's name, many articles come out. There's a time when I got scolded (by Zico) because of this."

Park Kyung commented, "I have been scolded (by Zico) many times too," but explained he couldn't help but talk about Zico since he is the most popular member. 

B-Bomb brought laughter as he joked, "He will probably call again if this makes headlines."
