How to Avoid Spam Submissions with an Online Form Builder

Did you know that nearly 28% of web form submissions are spam, causing businesses to lose time and miss genuine opportunities? If you use forms to collect leads or data, spam submissions can quickly become a big problem.

Because, spam submissions flood your inbox with fake entries, making it harder to spot real inquiries. But what if you could block these without making things harder for your users? That’s where an online form builder comes in.

In this article, we’ll cover online form builders, what spam submissions are, and how to stop them. You’ll learn simple techniques, from CAPTCHA to other methods, to build spam-free forms that keep your process smooth and efficient.

What Are Spam Submissions in The Context of Online Forms?

Spam submissions in online forms refer to unwanted or irrelevant entries submitted by automated bots, scripts, or even malicious individuals. These submissions typically aim to disrupt operations, collect user data, or promote fraudulent content.

Spam in forms affects various online platforms, including contact forms, sign-up pages, feedback forms, and order forms.

How spam submissions occur

1. Bots and automation: Malicious bots are programmed to crawl websites and submit forms automatically. These bots can bypass basic captcha systems and exploit vulnerabilities in poorly secured forms.
2. Human spammers: In some cases, humans manually submit spam to spread links or promotional content.
3. Exploitative scripts: Sophisticated scripts exploit weak form security, injecting malicious code or overwhelming servers with a high volume of submissions.

Characteristics of spam submissions

• Irrelevant information: Entries filled with gibberish or promotional content.
• Links to malicious websites: Embedded links redirect users to phishing or malware-infested sites.
• Fake contact details: Bogus email addresses and phone numbers.
• Excessive volume: Flooding forms to crash or slow down the system.

A report by Imperva in 2022 revealed that 42.3% of all internet traffic was from bots, with 27.7% being bad bots responsible for activities like form spamming.

Why Spam Submissions Are a Problem

Spam submissions are a common phenomenon for online platforms, directory websites, and businesses that rely on user-generated content. These submissions are not only disruptive but also have broader implications for the integrity, usability, and profitability of a platform.

i. Compromising user experience

Spam submissions clutter legitimate listings, making it harder for users to find the information they need. For example, in a job directory website, fake job postings can mislead job seekers and cause frustration.

According to a report by Statista, spam accounted for 45.6% of all email traffic in 2023, reflecting how pervasive the problem is across digital platforms. This volume translates to other forms of spam, including directory and form submissions.

ii. Damaging platform credibility

When users encounter spam listings, trust in the platform diminishes. For example, a restaurant directory overrun with fake or irrelevant entries risks losing users to competitors with cleaner, curated content. Platforms like Yelp and TripAdvisor spend significant resources to identify and eliminate spam reviews to maintain user trust.

iii. Impact on SEO and rankings

Spam submissions can negatively affect a website’s search engine ranking. Search engines like Google penalize websites with low-quality or duplicate content.

For instance, spam listings in a classified ads website could lead to keyword stuffing or the presence of irrelevant content, causing a drop in visibility.

iv. Financial loss

Spam submissions often divert resources that could be used for platform improvement. For example, businesses must invest in spam prevention tools or allocate time for manual moderation.

A study by Kapost estimated that companies spend $4 billion annually combating spam across various platforms.

Moreover, payment gateway misuse through fraudulent listings can lead to direct monetary losses.

v. Security threats

Spam submissions may contain malicious links or attachments that pose security risks. For instance, phishing attacks hidden within form submissions can compromise user data.

According to Verizon’s 2024 Data Breach Investigations Report, 68% of breaches involved human elements, often stemming from spam or phishing.

Effective Strategies to Avoid Spam Submissions with an Online Form Builder

Online forms are essential for collecting valuable data from users, but they are also prime targets for spam submissions.

Spam can overwhelm your database, skew analytics, and even disrupt business operations. Implementing robust strategies to prevent spam ensures data integrity, saves resources, and improves user trust.

1. Enable CAPTCHA verification

CAPTCHA is a proven method to reduce spam submissions by distinguishing between human and automated users. According to a survey by DataDome, implementing CAPTCHA can reduce spam submissions by up to 95%, ensuring your form remains secure.

Advanced CAPTCHA tools like Google reCAPTCHA offer seamless integration and improved user experience. These tools deter bots while keeping the process easy for genuine users, preventing drop-offs caused by overly complex verifications.

2. Use double opt-in for email submissions

Double opt-in ensures that users confirm their email addresses before being added to your system. Studies by HubSpot indicate this method reduces spam signups by 50%, improving the quality of collected data.

With double opt-in, users receive a confirmation email to verify their identity. This extra step discourages fake or malicious entries, protecting your database from invalid or harmful information.

3. Limit submissions per IP address

Restricting the number of submissions from a single IP address is a powerful way to prevent spam. Research from Akamai shows that spam attacks often originate from repetitive IP requests.

Implementing rate limiting ensures that genuine users can submit forms without hindrance, while suspicious activity from bots is blocked. This strategy creates a balance between usability and security.

4. Validate email and phone numbers

Automatic validation tools verify the authenticity of email addresses and phone numbers in real-time. A 2023 study found that such tools eliminate up to 70% of spam entries.

By integrating validation, you can ensure only legitimate contact details are accepted. This not only reduces spam but also enhances the overall quality of your lead database.

5. Employ honeypot fields

Honeypot fields are invisible to human users but can trap bots attempting to fill all form fields. Experts report that this simple technique blocks up to 90% of automated spam.

Unlike CAPTCHAs, honeypots provide a frictionless experience for users, keeping forms user-friendly while secretly thwarting malicious submissions.

6. Use advanced spam filters

Leverage AI-powered spam filters to detect and block suspicious activity. According to Imperva, these filters analyze submission patterns to flag spam in real-time.

AI-based systems continuously learn from spam behavior, improving accuracy over time. This dynamic approach ensures your forms remain protected against evolving threats.

7. Require user authentication

Mandating users to create an account before submitting a form can deter spam. Authentication creates an additional layer of security, ensuring that only genuine users can access and complete your forms. This method also builds a verified user base.

8. Regularly monitor and update forms

Regular form audits help identify and fix vulnerabilities that may allow spam. So, start proactive by updating plugins, adding new security measures, and reviewing analytics. A well-maintained form is less likely to become a target for spammers.

9. Block disposable email addresses

Blocking submissions from disposable email services like Temp-Mail or 10-Minute Mail can filter out low-quality entries. This strategy eliminates spam attempts from untraceable sources.

Therefore, use email validation APIs to detect and block such addresses in real-time. This ensures you capture only authentic and useful data from legitimate users.

10. Leverage form submission analytics

Form analytics provide insights into suspicious behavior, such as unusually high submission rates. Tools like Google Analytics help detect patterns that may indicate spam activity.

How to Choose the Right Online Form Builder

Online form builders are essential tools for collecting data, managing workflows, and enhancing user interaction on websites.

Selecting the right form builder can significantly impact your ability to meet your goals efficiently. Here’s a comprehensive guide to help you make an informed decision.

i. Define your purpose and requirements

The first step in choosing an online form builder is understanding your specific needs. Are you creating simple contact forms, conducting surveys, or managing event registrations?

Knowing the purpose of your forms will help you narrow down your options. Additionally, list the features you require, such as conditional logic, integrations with other tools, or payment processing capabilities.
