2. Report the account: Click on the profile or message, then:

1. Select “Find support or report.”
2. Choose the reason (e.g., “Fake account,” “Spam,” or “Pretending to be someone”)

Top signs of bot on Facebook accounts in 2025

They include:

1. Suspicious profile information: A suspicious or incomplete profile is one of the first red flags for a bot. Look for:

1. Generic names: Bots use generic or popular names like “John Smith” or “Sarah Miller.”
2. Profile pictures: Reverse image search the profile picture on Google Images or TinEye. Bots use stock photos, celebrity pics, or hijacked images.
3. No personal details: Real individuals quote schools, workplaces, homeowners, or family members. Bots will leave these out.

2. Unusual posting patterns: Facebook bots post differently than real individuals. These are the warning signs:

1. Over-posting: posting 24/7 every other minute is bot automation for certain.
2. Reposting content: Bots will repost the same material in groups or on pages.
3. No personal photos: A link-only, meme-only, or advertisement-only timeline is suspicious.

3. Unnecessarily excessive friend requests: If you receive a friend request from someone with no mutual friends, no link, and a weird profile, it is likely a bot. Other signs are:

1. Mass adding dozens of friends at once
2. Shooting you a message as soon as they’ve befriended you
3. Rough grammar or unnaturally formal wording in messages

4. Strange comments or responses: Spambots often flood comment areas of public posts. They typically post:

1. Generic: “Nice post!” or “Wow, amazing!”
2. Out of context: Not related to the post
3. Promotional: With links or emojis referencing shady sites

5. Inconsistent language or grammar: Poor writing is one of the biggest giveaways. Spambots will:

1. Use broken English
2. Mix unrelated hashtags
3. Translate text awkwardly with machine translators

Example: “Hello, dear. I am looking for a real relationship. I am a good man from a respectable family and a nation of love.”

6. Membership in questionable groups or pages: Bots also join big groups to spam them with data. Make sure the profile:

1. Is a member of several irrelevant groups
2. Encourages suspicious links or items
3. Tends to tag strangers on group posts

7. Manipulative or false interaction: Facebook bots might pretend to engage, but it’s often a giveaway:

1. Fake likes and shares: Many likes, few comments
2. Comment farms: “Great,” “Thanks,” or dozens of emojis as comments
3. Irrelevant action: Commenting on something not related

8. Messenger spam: Bots can also message you on Facebook Messenger with:

1. Unusual links
2. “You won a prize!” scams
3. Asking for money or data
4. Flirting attempts that escalate to phishing links

9. Third-party tool assistance: Some tools and extensions help detect bots:

a.) Fake Profile Detector browser extensions

b.) Google Reverse Image Search

10. Report and block bots: If you are convinced someone is a bot:

a.) Report the profile to Facebook.

b.) Block the account to prevent further contact.

c.) Alert friends if they have common connections.

Case study: COVID-19 Misinformation on Facebook (2020–2021)

During the pandemic, Facebook became a significant platform for health misinformation, much spread by bots and fake accounts.

Research by Carnegie Mellon University and the Center for Countering Digital Hate (CCDH) found that bots were behind conspiracy theories and anti-vaccine content.

A 2021 CCDH report identified the “Disinformation Dozen”—12 people responsible for nearly 65% of anti-vaccine posts, amplified by bots using tactics like spamming, impersonating doctors, and mass posting.

This content fueled vaccine hesitancy and was declared a public health threat by the U.S. Surgeon General.

In response, Facebook removed over 20 million misleading posts and suspended bot accounts.

The case highlights how bot-driven disinformation can harm public health and the urgent need for users to verify content online.

How Facebook is battling bots

It includes:

1. Artificial intelligence (AI): Utilizes machine learning to detect malicious activities such as repeated posting, suspicious logins, and sending many friend requests.
2. Behavior analysis: This method detects accounts through behavioral patterns, such as repeatedly logging in from multiple places or excessively tagging and posting objects.
3. Image recognition: Detects and blocks the use of stock images, celebrity images, or AI-generated images often used by bots.
4. Spam keyword filters: Inspects comments and posts for normal, promotional, or phishing-type words.
5. Content moderation teams: Apply human reviewers to analyze borderline cases brought up by algorithms.
6. Account verification processes: Requests additional verification (e.g., phone numbers or IDs) for suspicious accounts.
7. User reporting tools: Request users to report suspicious behaviour, which helps improve detection accuracy.
8. Ongoing updates: The threat and bot tactic detection models are constantly updated.

Despite these, Millions of bots continue to be manufactured daily, so user vigilance is paramount.

As Facebook grows stronger, so does the sophistication and scale of bot activity.
