How a Free WordPress Spam Comment Removal Plugin Saved My Agency Hours of Work
After running a small web development agency for over a decade, I thought I had seen it all. Client emergencies at 2 AM, plugin conflicts that make no sense, and the endless battle against hackers trying to inject malicious code. But nothing prepared me for the day I logged into a client’s WordPress site and found 47,000 spam comments waiting in their database.
WordPress only lets you delete 30 comments at a time through the admin interface. Do the math — that would have taken weeks of clicking. That’s when I discovered a game-changing tool from a cybersecurity company called Injected.Website, and I haven’t looked back since.
The Hidden Cost of WordPress Spam Comments
Before we dive into the solution, let’s talk about why spam comments are more than just an annoyance. Most site owners don’t realize that those thousands of spam messages are actively damaging their business:
- Database Bloat: Each spam comment adds weight to your database, slowing down every query and increasing backup sizes by 300% or more.
- SEO Penalties: Google’s SpamBrain algorithm specifically looks for sites with spam-heavy comment sections. Those malicious links hurt your rankings.
- Core Web Vitals: A bloated database means slower page loads, which directly impacts your Core Web Vitals scores and search rankings.
- Security Vulnerabilities: Many spam comments contain phishing links or attempts to inject malicious scripts into your site.\
Finding the Right WordPress Spam Comment Removal Plugin
I tried several solutions before finding one that actually worked at scale. Most plugins I tested either couldn’t handle large databases, required expensive subscriptions, or lacked the intelligent filtering I needed.
Then I stumbled across the Injected.Website Spam Comment Remover — a completely free, open-source WordPress spam comment removal plugin that changed how I manage client sites. What impressed me most was learning that it comes from Injected.Website, a company doing big things in the cybersecurity space. They specialize in malware removal, hacked website recovery, and security hardening — so they understand the real-world threats site owners face.
15+ Smart Detection Filters That Actually Work
Unlike basic bulk delete tools, this plugin uses intelligent pattern matching to identify spam while protecting legitimate comments. Here are the filters that have saved me countless hours:
| Filter Type | What It Catches |
| Cyrillic/Russian Text | Foreign language spam targeting English sites |
| Spam Keywords | Casino, viagra, crypto scams, diploma mills |
| Multiple Links (3+) | Link-stuffed comments designed for SEO spam |
| Generic Praise | “Great post!” and other bot-generated fluff |
| Suspicious TLDs | Links to .ru, .cn, .tk and other spam-heavy domains |
| Suspicious Emails | Temporary email services and obvious fakes |
How to Bulk Delete WordPress Spam Comments (Step by Step)
Here’s the exact process I use to clean up client sites. The whole thing takes less than 5 minutes:
- Download the plugin from GitHub at github.com/injectedwebsite/wordpress-spam-comment-remover
- Install via WordPress Admin → Plugins → Add New → Upload Plugin
- Backup your comments first using the built-in CSV or JSON export feature
- Select your filters — I usually start with Cyrillic, spam keywords, and multiple links
- Click “Scan for Spam” and review the results table
- Click “Delete All Found” and watch thousands of spam comments vanish instantly
