3 ways to stop spam comments on Facebook 

Facebook is at the front and center of e-commerce growth. Apart from connecting billions of people through its platform, the social media giant also hosts millions of businesses to maintain brand presence and generate revenue. Brand’s connect with their audience by sharing content through pages, advertisements and groups. And the audience expresses their views and interacts with the brand through the comments section. 

Well, this is all good until Facebook spam comments impact this meaningful communication process by posting irrelevant, and malicious content. 

In this CommentGuard article, we’ll discuss 3 ways to stop spam comments on Facebook.

What are Facebook spam comments?

Imagine having a meaningful conversation with your friends, and suddenly someone barges in, shouting things completely unrelated to your discussion. Facebook spam comments do the same. They are unwanted, irrelevant or deceptive comments that clutter the comments section of your posts, ads and groups. 

Spam comments on Facebook posts are a result of bot activity automated by spammers and include, plain text, emojis, GIFs, generic advertising or malicious links.  Spammers do this to grab the attention of genuine users to exploit their information, defame a brand, or promote their causes. 

How Facebook spam comments affect your brand?

Facebook spam comments affect your brand significantly. Not only do they dilute the genuine engagement on your posts but also damage your brand reputation. If continued, customers doubt your authenticity, and moderation efforts, eventually enticing them to consider alternatives. And given the fierce competition in even the smallest of the niches, losing quality customers can put a major dent in your business. 

Diminished credibility and trust 

Creating and maintaining a successful brand relies a lot on the credibility and trust users have in your brand. This means offering high-quality product/services, interacting with the audience and ensuring a safe and comfortable environment for them on your social accounts.

Discussions around your brand, its products happen in the comments section where customers share their opinions and participate in meaningful conversations with others. 

But spam comments ruin this experience with irrelevant comments which are not only shady, but also malicious in nature. 

Encountering a lot of them on your brand’s post, page or group can make your customers uncomfortable to have genuine discussions and they might also fall victim to scams. This eventually degrades their trust in your brand and raises questions if you are putting enough effort in maintaining a spam-free environment.

Negative user experience 

Imagine having a terrible experience with a brand. Whether you are a new customer or an existing one, the experience will stick with you, every time you interact with the brand. 

Well, you don’t want this to happen to your customers. 

Facebook spam comments clutter the comment’s section, with irrelevant profanity, making it tough for users to find and engage in genuine discussions. Apart from text and emojis, spammers also leave links on your content. These are malicious links clicking on which exposes a user’s information or automatically downloads viruses on their devices. 

Such experiences lead to a poor user experience and eventually creates a negative word-of-mouth about your brand. Your existing customers can easily get frustrated, and consider other brands on the platform.

Reduced user engagement 

Meaningful user engagement is a major factor considered by the Facebook algorithm to suggest and promote your content to audiences similar to yours. Having an active comments section where users take part in quality discussions also helps your page get an edge over your competitors while attracting new leads. 

Unfortunately, spam comments reduce user engagement on your content by creating clutter with irrelevant and potentially harmful comments and when users encounter this clutter, they might avoid participating in discussions.

Types of Facebook spam comments 

When dealing with Facebook spam comments, it’s critical to understand their types and purpose. This helps you take the most appropriate actions to stop them from affecting your brand on the platform.

Generic advertising 

Generic advertising spam comments involve promoting products or services which are unrelated to your posted content. Spammers use this tactic to advertise their offerings and gain visibility from your audience interactions. 

For instance, if you’ve posted a coffee recipe, a generic advertising spam comment might be promoting a completely unrelated product, like weight loss supplements or financial services.

Clickbait and links 

These are spam comments containing malicious links with the goal of enticing users to click on them. While these links appear safe, clicking on them redirects users to phishing sites and irrelevant content, including adult sites, financial scams and more. 

For instance, a clickbait spam comment might claim to offer exclusive content or offers, but the link leads to a landing page, attempting to steal personal information.

Fake engagement 

These are comments generated by automated bots and include generic or irrelevant content. Fake engagement comments appear genuine in the comments section, but a closer look would reveal spam. 

For instance, a fake engagement comment might consist of generic phrases like “Great post!” or “Amazing cat!” without any specific reference to the post’s content. 

How to block spam comments on Facebook?

Now that you know how Facebook spam comments affect your brand, let’s discuss some methods to stop them. By implementing correct measures, you can maintain your brand reputation and health on the platform.

Moderate comments

One of the best ways to deal with Facebook spam comments is imposing strict moderation on your comments section. This involves regularly monitoring comments on your posts, advertisements and groups to detect spam. 

You can use Facebook’s native keywords filtering setting to filter comments containing specific keywords from a list you provide. With this approach, not only can you identify spam comments quickly but also reduce the manual effort needed for moderation.

Here’s how you can set keyword filters for your Facebook business page:

  • Log in to Facebook, and select the Page. 
  • Press on your Page photo > “Settings and privacy,” > “Settings,” >  “Privacy.”
  • Tap on “Public posts,” and under the Moderation section, click on the Edit option of the Hide comments containing certain words from your Page.
  • Add keywords separated by commas, and emojis or paste a list or upload from .CSV.
  • Click Save

This filter will be automatically applied to your ads.

Utilize Facebook’s reporting system

Another method of stopping Facebook spam comments is reporting the spam accounts. When you report an account, Facebook evaluates their action against its community guidelines. If found guilty, the social media giant either restricts or bans them from the platform. 

This Is also effective because Facebook strictly discourages the use and presence of automated bots on its platform. As the spam comments are a result of bot action, reporting them to Facebook helps you get rid of them and contribute to other brand’s presence. 

Here’s how you can do it:  

  • Go to the comment that you want to report.
  • Click on the three-dotted icon > “Report comment.”
  • Pick an option why the comment is spam or click on Something else to search for more.


While both the previous methods help you apply moderation and report spammers, they don’t provide you the freedom to manage the comments section with minimal effort.
