+## DIP61: Ability to delist rogue creators
+
+[不正なクリエイターの上場廃止機能(Ability to delist rogue creators.)](https://community.devprotocol.xyz/t/ability-to-delist-rogue-creators/258)
+
+## Sentence Summary
+
+This problem solves the problem of not being able to unauthenticate with the market except for the property author.
+
+## Paragraph Summary
+
+This DIP proposes a feature that allows the market owner to freely deauthenticate the property.
+
+## Component Summary
+
+Modify the onlyLinkedPropertyAuthor modifier.
+Currently, an error occurs unless the sender is an author of the property.
+This will be changed so that the error will not occur if the "sender is the author of the property or the owner of the market".
+
+## Motivation
+
+There have been cases where development repositories have been deleted or made private. We provide this feature to deal with this.
+
+## Specification
+
+### Proposed Code
+
+I'll implement it now.
+
+### Test Cases
+
+・Only the market owner and the property's author have the authority to execute the market deauthentication function.
+・Check that the following conditions are met for the deauthenticated property.
+　・Staking cannot be performed.
+　・Staking can be canceled.
+　・Creator reward and staking reward cannot be obtained.
+
+### Security Considerations
+
+Make sure that only the owner and the author of the property to be deauthorized are authorized to execute the Market deauthorization function.
+(Author-based deauthentication has already been implemented.)
