The platform provides a user blocking feature. Users may choose to block other users at their discretion. Blocking produces the following effects:
- Content Filtering: All works, coloring works, inspiration content, etc., of the blocked user will no longer appear in the blocker's content lists
- Comment Restriction: Blocked users cannot post comments under the blocker's works, topics, or inspirations
- Immediate Effect: The block takes effect instantly, and the blocked user's content will be immediately removed from your feed
- Follow Termination: The block operation will automatically cancel the follow relationship between both parties (including the blocker following the other and the other following the blocker)
- Reversible: You may unblock at any time; after unblocking, the above restrictions are restored immediately, but the automatically canceled follow relationships will not be automatically restored
6.2 Blocking Notifies the Platform
To better maintain community safety, when you block another user, the platform will automatically receive a notification of the block (including information about the blocker and the blocked user, but not the reason for blocking). The platform will use this notification to review the blocked user's content, and if violations are found, will take action in accordance with Section X (Breach of Agreement) of this Agreement.
6.3 User Rights and Obligations
- Right to Block: You have the right to decide at your own discretion to block or unblock any other user without providing a reason
- Unidirectionality: Blocking is a unilateral action; A blocking B is not equivalent to B blocking A
- Prohibition of Abuse: You must not use the blocking feature to circumvent platform rules (e.g., blocking administrator or content moderation accounts to prevent their normal duties)
- Self-Management: You may view and manage blocked users in the "Blocked List" and decide whether to unblock them at your discretion
6.4 Data and Privacy
- Block Records: The block relationship and block time are recorded and retained by the platform to implement the feature and content filtering
- No Notification to Blocked User: The platform will not proactively notify the blocked user that they have been blocked (silent mechanism)

- Data Retention: After unblocking, block records may still be retained by the platform for audit or statistical purposes. For detailed rules, please refer to the Privacy Policy
6.5 Content Display
- Server-Side Filtering: Content from blocked users is automatically filtered on the server side and will not appear in the blocker's content lists. This is a technical service provided by the platform and does not constitute an infringement of the blocked user's content rights
- Filtering Scope: The filtering scope includes but is not limited to: artwork lists, coloring lists, inspiration lists, collection artwork lists, color group lists, etc.
- Filtering Is Not Deletion: Content from blocked users is only invisible to the blocker and remains normally visible to other users
6.6 Comment Restrictions
- Comment Prohibition: When a blocked user attempts to post a comment under the blocker's works, topics, or inspirations, the platform will reject the comment request
- Existing Comments: Comments posted before blocking are unaffected and will continue to be displayed normally (removal requires reporting or other mechanisms)
- Restriction Notice: When a blocked user attempts to comment, the platform will return a prompt message but will not disclose who blocked them
6.7 Follow Relationships
- Automatic Unfollowing: Upon blocking, the platform automatically cancels the follow relationships between both parties. This is an irreversible ancillary action
- No Automatic Restoration: After unblocking, the previously automatically canceled follow relationships will not be automatically restored; users must manually re-follow
- Mutual Unfollowing: Blocking results in the cancellation of bidirectional follow relationships, i.e., both A following B and B following A are canceled simultaneously
6.8 Disclaimer
- Feature Availability: The platform makes every effort to ensure the normal operation of the blocking feature, but shall not be liable for temporary failure due to force majeure such as technical failures
- Content Filtering Omissions: Due to technical reasons such as caching and delays, content from blocked users may briefly appear in lists; the platform shall not be liable for this
