The Scenario:
Last month, we had a particularly nasty wave hit us. Suddenly, dozens of new registrations popped up, followed by a torrent of gibberish posts across multiple forums, all within a short timeframe. It was clearly automated, and it started late evening when I was just winding down.
My First Hour Action Plan:
1. Stop the Bleeding (5-10 minutes)
First, you need to turn off registration temporarily. This stops the immediate influx of new spam accounts. Go to ACP → General → Board settings and set Enable board to No, or at least Allow user registration to No. I prefer disabling the board entirely for a moment, adding a quick message that we're dealing with technical issues. This sends a clear signal to both spammers (who will just see a disabled board) and legitimate users (who will understand why they can't post).
2. Identify and Ban (15-20 minutes)
Next, I jump into the user list. In ACP → Users and Groups → Manage users, sort by registration date. Look for patterns: unusual usernames, specific domains in email addresses, or common IPs. If you have the dmzx Notify Admin on Registration extension enabled, your email inbox will be a good first source for spotting the recent problematic registrations.
- Bulk Delete/Ban: Select all the obvious spam accounts. Ban them by IP address and email if possible. Often, spammers use a range of IPs or a temporary email service. Banning the IP range can be effective.
- Check IP/Email Associations: For more subtle spammers, use the dmzx User Check extension. This is a lifesaver. You can quickly search for users by IP address, email, or even username patterns to see if a single spammer has created multiple accounts. If you find duplicates, you can clean them up in one go.
Now for the posts. This can be tedious, but it's essential for your members' experience.
- Recent Topics/Posts: Head to the ACP → Maintenance → Manage posts section. Sort by newest posts. This helps you quickly find and delete or prune the spam topics and replies. If the spam posts are all by the same handful of users, deleting those users will often take their posts with them.
- Database Backup (Optional but Recommended): If the spam is truly widespread and you're unsure about deleting, a quick database backup before major deletions gives you a safety net.
Once the immediate threat is contained and the worst of the mess is cleaned up, re-enable registrations or the board (ACP → General → Board settings).
- Review Anti-Spam Measures: This is the time to consider what allowed the spam through. Did your CAPTCHA fail? Do you need to enable dmzx User Check to catch duplicate accounts more effectively? Or perhaps change your registration question to something harder for bots to solve?
What immediate steps do you usually take when your board gets hit by a spam attack?
