Suppose Kakao identifies a case where a user used the service in a way not permitted by KakaoTalk, by analyzing a report or complaint from other users or the service environments or usage patterns of the reported person.

In particular, Kakao may restrict its users from accessing those accounts judged to harm service provision or severely impede stable operation, for example, causing malfunction of service facilities and destruction or disruption of service systems.
