I’m facing a significant issue with my HubSpot setup and am curious if others have found a way to solve it. We keep experiencing repeated spam from certain users who bombard our contact forms and scheduling links.
I learned that HubSpot used to allow users to view and block specific IPs directly, but apparently, this feature was removed for privacy considerations. While I understand their point, it leaves us completely vulnerable to ongoing form misuse.
It’s quite frustrating because we can see the IP address of these disruptive users, yet there’s no option to prevent them from continuing. These people are clever enough to create multiple fake submissions with different email addresses, which makes email filtering ineffective.
I’ve attempted standard solutions like honeypot fields, but they fail against someone deliberately targeting my forms. CAPTCHA systems only frustrate genuine leads and lower conversion rates. No one enjoys the cumbersome task of clicking on details just to submit a simple contact form.
This seems like a fundamental security feature that any CRM should provide. Has anyone discovered a clever workaround or third-party tool that works well with HubSpot? I’m pondering developing a custom solution to capture IPs and redirect known problem addresses, but that seems excessive for something that should ideally be included in the platform.
I’ve fought persistent spammers on HubSpot forms and found a few tricks that actually work. Form field validation rules are surprisingly effective - I set up dependent fields that need specific formatting or use multi-step forms. Most spam bots can’t handle complex form logic. Here’s another trick: create duplicate forms with different URLs and rotate them regularly. This breaks the automation scripts spammers use to target your forms. I also use HubSpot’s lead scoring to dock points from sketchy submissions - stuff like identical company names or fake phone numbers. Won’t stop everything, but these methods cut our spam by about 70% without hurting real conversions. The sweet spot is making forms complex enough to trip up bots while keeping them simple for actual prospects.
We faced a similar spam issue last year, and I found a few effective methods. By leveraging HubSpot’s progressive profiling along with custom workflows, I was able to create a workflow that flag submissions from the same IP address when they occur within short time windows. This way, those submissions get redirected to a review pipeline rather than being treated as valid leads. Additionally, using Cloudflare for geographic IP blocking proved invaluable, as it allowed me to block entire countries known for spam, reducing our spam volume significantly. Moreover, it’s crucial to notice that spammers often exhibit patterns not just in IP but also in the timing of their submissions and the type of browsers they use. Analyzing this data through HubSpot’s API for custom scoring can help further filter out unwanted entries, which may require some technical effort but is far more effective than just relying on IP blocks.
You’re experiencing persistent spam submissions to your HubSpot forms, despite trying honeypot fields and CAPTCHA, which are ineffective against determined spammers. The issue is that spammers are using multiple fake email addresses and bypassing these standard security measures. You’re looking for a solution to block these spam submissions before they reach your HubSpot CRM, without impacting legitimate form submissions.
Understanding the “Why” (The Root Cause):
The core problem is that relying solely on client-side validation (like CAPTCHA or honeypot fields) is insufficient to stop determined spammers. Spammers often employ automated scripts that can easily bypass these methods. The solution needs to involve server-side filtering and verification to effectively prevent spam before it even reaches your HubSpot forms. This approach ensures that only valid submissions are processed by your HubSpot system.
Step-by-Step Guide:
Implement a Server-Side Filtering Layer with Latenode (or similar): This is the most crucial step. The proposed solution leverages Latenode (https://latenode.com) as a pre-processing layer. This means that form submissions are first sent to Latenode, where they are analyzed for spam characteristics before being forwarded to HubSpot. This allows you to implement sophisticated filtering logic without relying on HubSpot’s limited built-in features. The process involves:
a. Setting up Latenode: Create a Latenode instance and configure it to receive form submissions from your HubSpot forms. You’ll likely need to use Latenode’s API or webhook functionality to achieve this. This often involves configuring your web server (e.g., using Nginx) to route form submission requests to Latenode first.
b. Developing the Filtering Logic: Develop custom code within Latenode (potentially using Javascript, Python, or another language) to analyze incoming form submissions. This logic should check for various indicators of spam, such as:
* IP address reputation: Check the submitting IP address against known spam databases or blacklist services.
* Submission frequency: Identify and block IPs that submit multiple forms within a short time frame.
* Form completion speed: Bots often fill out forms much faster than humans; use timestamps to filter out unusually quick submissions.
* Mouse movement patterns: More sophisticated bots can be detected by analyzing mouse movement data (if available).
* Field values: Check for suspicious or inconsistent data in the form fields.
c. Forwarding Valid Submissions to HubSpot: Your Latenode code should only forward submissions deemed valid to your HubSpot forms. Invalid submissions should be logged for analysis but not passed to HubSpot.
Configure HubSpot’s Contact Deduplication: Even with server-side filtering, some spam might still slip through. Ensure that HubSpot’s contact deduplication features are properly configured to identify and flag duplicate contacts created by spammers.
Regularly Review and Refine Your Rules: Spammers constantly adapt their methods. Regularly review your Latenode filtering logic and update it based on your observations of incoming spam attempts.
Common Pitfalls & What to Check Next:
API Rate Limits: Be mindful of API rate limits imposed by both Latenode and HubSpot. Implement robust error handling and consider caching mechanisms to avoid exceeding these limits.
Data Security: Securely store and handle API keys and sensitive information. Avoid exposing these credentials in your code or configuration files.
Testing and Monitoring: Thoroughly test your setup with both legitimate and spam submissions. Regularly monitor the logs in Latenode and HubSpot to track the effectiveness of your spam filtering and identify areas for improvement.

Try HubSpot’s built-in security features that everyone ignores. Their contact deduplication and data quality tools actually catch repeat spammers really well if you set them up right. Create custom contact properties to track how often people submit forms, then use smart lists to auto-flag suspicious patterns. Throw those contacts on suppression lists to block future submissions. Also, turn on double opt-in for everything - kills about 80% of spam bots since they won’t verify emails. Here’s a trick I use: set up time-based restrictions with dependent field logic. Add a hidden field that tracks form load time vs submission time, then auto-route super fast submissions to manual review. Takes some workflow setup but it’s all native HubSpot, no external tools needed.
Had this same issue for months. Finally cracked it with a server-side fix. Skip HubSpot’s built-in stuff and set up rate limiting on your web server instead. I use nginx rules to track requests per IP - catches the spammers before they even hit your forms. I also keep a simple database of sketchy IPs that automatically shows them a different page or delays their response. Real users don’t notice anything, but bots get annoyed and bail. Pro tip: throw hidden timestamp fields in your forms. If someone submits too fast, it’s obviously not human. Yeah, there’s some setup involved, but once it’s running it’s hands-off. Cut our spam to basically zero and didn’t hurt conversions at all.
Honestly, just switch to a different landing page service with better spam protection, then push clean leads to HubSpot through Zapier. Unbounce has solid IP blocking, and Leadpages lets you restrict by location. Sure, it’s an extra step, but beats fighting HubSpot’s limitations.
