❓ Reader Policy and Frequently Asked Questions (FAQ)

This document introduces the basic principles of personal information and data processing upon account deletion, and the service activity restriction policy.

🚪 Q1. What happens to my comments and guestbook posts when I delete my account?

The blog system applies an author anonymization policy to simultaneously protect the user's privacy and maintain the integrity of dialogue threads within the site.

💡 Data Processing Principles Upon Deletion

1. Personal Identification Data Removal:
   • When you delete your account, your active session and social login connection information are immediately and safely removed from the authentication system. However, for preventing abuse and security audits, minimal data containing the email and social ID connection information at the time of deletion is backed up in a segregated internal deletion log table (deleted_users). This log information is for internal administrative use only, and is completely anonymized and hidden on public pages to prevent any reverse-tracking of the author.
2. Content Data Retention:
   • Your comments and guestbook messages remain on the screen to preserve the context of past discussions and conversations.
3. Nickname Anonymization:
   • The link between your account and your posts is severed, and the author name automatically switches to "Unknown". This prevents reverse-tracking of the actual author's identity.

• Note: If the administrator manually deletes your membership record entirely, your comments and guestbook entries may also be removed.

🚪 Q2. Can I sign up again immediately after deletion or withdrawal?

• Voluntary Withdrawal:
  • If you voluntarily delete your account, you can sign up again immediately using the same email or social account without any grace period.
• Activity Ban (Ban) State:
  • If your account is banned due to policy violations, you cannot sign up again with the same email because the email information still exists in the database.
• Forced Deletion (Kick) State:
  • If your account is forcibly deleted (Hard Deleted) by an administrator, the existing information is completely removed from the authentication tables, making it technically possible to sign up again with the same email immediately.
  • Although the email and social ID information from the time of the kick are preserved in the internal deletion log (deleted_users), there is currently no automated system block logic that compares this log at the time of registration to restrict sign-ups.
  • Therefore, to physically and completely prevent a malicious user from signing up again, the account should be kept in a 'Banned' state rather than being forcibly deleted. (In a banned state, the email remains in the database, preventing re-registration due to the unique email constraint.)

🚫 Q3. My account has been restricted (banned) or forced out (kicked).

Checklist when your service usage is restricted (banned) or deleted (kicked) due to policy violations (such as posting spam or offensive content).

💡 Core Checklist for Activity Restrictions

1. Activity Ban (Ban):
   • Status: Your login state remains active, but direct interactions such as posting comments, nested replies, or guestbook entries are temporarily or permanently restricted.
   • Checking Reasons: When restricted, a notice saying "Banned users cannot write comments." will appear in the comment form area, and you can view the specific reason and the expiration date of the restriction.
2. Forced Deletion (Kick/Delete):
   • Status: The login account itself is completely deleted (Hard Deleted) from the database.
   • Behavior: Once kicked, your active login session is immediately terminated. Subsequent login attempts will treat you as a new user with no registration history. Depending on the deletion behavior set by the administrator, comments you wrote may either be deleted entirely or anonymized as 'Unknown'.
