Overview

The Blacklist Control Center allows administrators to manage banned IPs, domains, and email addresses. This powerful moderation tool helps protect your site from spam submissions, malicious users, and unwanted content by blocking specific identifiers at multiple levels. It includes bulk blocking via keyword/domain lists, database scanning to retroactively mark existing blacklisted content, and individual entry management.

How Blacklisting Works

Individual Entries (tblBlacklist)

When you add an entry to the blacklist:

  1. Entry is stored in tblBlacklist with a type field
  2. All galleries matching the criteria are updated:
  • accept is set to 'Blacklisted'
  • newpost is set to 'BlackList'

Matching logic by type:

  • email: Matches gallery's email field exactly
  • ip: Matches gallery's IP field exactly
  • domain: Matches if gallery URL contains the entry
  • Any/All: Matches email, URL, or IP containing the entry

 

Bulk List (theblacklist.txt)

When you run Scan & Blacklist Gallery Database:

  1. Reads all comma-separated entries from theblacklist.txt
  2. For each entry (if length > 5 characters):
  • Checks domip field
  • Checks if url contains entry
  • Checks if email matches entry
  • Checks if ip matches entry
  1. Updates matching galleries to accept='Blacklisted'

Error Messages & Troubleshooting

Common Errors

Error Message Cause Solution
"ERROR: [SQL error]" Database query failed Check database connection, table exists
Blank scan results No matches found Verify bulk list has entries > 5 characters
Entry not saving File permission issue Ensure ct/dat/theblacklist.txt is writable

Troubleshooting

Problem: Bulk list changes not saving
Solution:

  • Verify ct/dat/theblacklist.txt exists and is writable (644)
  • Check for trailing commas that may cause parsing issues
  • Ensure entries are properly comma-separated

 

Problem: Galleries not getting blacklisted
Solution:

  • Verify entries are longer than 5 characters
  • Check that the entry matches actual gallery data
  • Use exact matches for IPs and emails
  • Use partial strings for domain blocking

 

Problem: "Remove" not working
Solution:

  • Verify JavaScript is enabled
  • Check browser console for errors
  • Ensure the entry has a valid ID in the database

 

  • Gallery Review (ct/admin/admin.php) - View and manage blacklisted galleries
  • Partner Control (ct/admin/preferred.php) - Manage trusted partners (opposite of blacklist)

Tips & Best Practices

 

Tip:
Use partial domain names: For broad blocking, use badsite.com instead of http://www.badsite.com/page. This catches all variations of the domain.

 

 

Tip:
Regular scans: Run "Scan & Blacklist Gallery Database" periodically to catch any galleries that were added before you added a blacklist entry.

 

 

Warning:
Be careful with generic keywords: Blocking common words like "free" or "hot" may catch legitimate galleries. Use specific terms.

 

 

Tip:
Export before changes: Copy the Export List before making major changes to the bulk list. This lets you restore if needed.

 

 

Note:
Blacklisting vs Deleting: Blacklisting marks galleries for review; you can pardon them later. Deleting is permanent.
