Group Block B's member Zico showed his anger towards his stalker fans.

"I said this over and over again. Invading my private space is nothing but abuse. This is not love from a fan in any way," wrote Zico on his Twitter on Tuesday.

He also retweeted a post by a producer that read, "I don't know how they knew this is Zico's workshop and keep coming but you come and throw trash away here and put post-its on the door. It's all recorded on the CCTV. This isn't private space and other people use it too, don't be such a harmful person."
