How to validate registrations using CleanTalk API with BVScript

Lately, we sometimes get questions like “The code samples on GitHub are written in C#, they don’t seem to convert to VB. Do you have any code sample for visual basic ?”

The good news is that now we have! The project below demonstrates how to use the Cleantalk API with VBScript to validate registrations. Feel free to ask any questions – we’re here to help.

Requirements

Register a Cleantalk account https://cleantalk.org/register?product=anti-spam
Obtain the access key from the CleanTalk account https://cleantalk.org/help/add-website

Usage

1. Place the code of Cleantalk class in your VBScript file.

 ```vbscript
 Class CleantalkClass
     Private auth_key
     Private check_message
     Private user_email
     Private user_ip
     Private user_name
     Private user_js_state
     Private user_submit_time
     Private form_event_token
     Private response
     Private verdict
     Private codes
     Private comment
     ... other class code
     ... other class code
   else
        validateResponse = false
   end if
     end function
  
  end class
 ```

2. Initialize the Cleantalk class instance, use your own access key when instantiating.

Dim Cleantalk : Set Cleantalk = (New CleantalkClass)("your_access_key", "check_newuser")

3. Set user data when the logic is ready to check the user.

Cleantalk.setUserEmail("stop_email@example.com")
Cleantalk.setUserIP("10.10.10.10")
Cleantalk.setUserName("John Doe")
Cleantalk.setUserJSState("1")
Cleantalk.setUserSubmitTime("5")
Cleantalk.setFormEventToken("a_32_symbols_event_token_value")

4. Send request to the API.

Send request to the API:

5. Validate the response.

If Cleantalk.validateResponse Then
    If Cleantalk.getVerdict = 1 Then
        WScript.Echo "Validation success. User is allowed."
    Else
        WScript.Echo "Validation success. User is blocked. Reason: " & Cleantalk.getCodes & " " & Cleantalk.getComment
    End If
Else
    WScript.Echo "Validation failed. Code: " & Cleantalk.getCodes & " Comment: " & Cleantalk.getComment
End If

Important! Do validation every time after response gathering.

Functions

setUserEmail(email)
setUserIP(ip)
setUserName(name)
setUserJSState(jsState)
setUserSubmitTime(submitTime)
setFormEventToken(eventToken)
sendRequest()
validateResponse()
getVerdict()
getCodes()
getComment()

Example

Dim Cleantalk : Set Cleantalk = (New CleantalkClass)("your_auth_key", "check_message")

Cleantalk.setUserEmail("user@example.com")
Cleantalk.setUserIP("192.168.1.1")
Cleantalk.setUserName("John Doe")
Cleantalk.setUserJSState("0")
Cleantalk.setUserSubmitTime("0")
Cleantalk.setFormEventToken("your_event_token")

Cleantalk.sendRequest

If Cleantalk.validateResponse Then
    If Cleantalk.getVerdict = 1 Then
        WScript.Echo "Validation success. User is allowed."
    Else
        WScript.Echo "Validation success. User is blocked. Reason: " & Cleantalk.getCodes & " " & Cleantalk.getComment
    End If
Else
    WScript.Echo "Validation failed. Code: " & Cleantalk.getCodes & " Comment: " & Cleantalk.getComment
End If

Implementing of BotDetector JavaScript library

To use the BotDetector JavaScript library, you need to include the script in the HTML of the page.

<script src="https://moderate.cleantalk.org/ct-bot-detector-wrapper.js"></script>

This script will automatically detect the form submission event and send the data to the Cleantalk API.

Please note, that the script does not perform any checks, just sends the user’s frontend data (like JavaScirpt state, mouse position etc.) to the API.

Example

<!DOCTYPE html>
<html lang="en">
   <head>
   <meta charset="UTF-8">
   <title>Register</title>
   <!--Bot-detector JS library wrapper. This script must be added to the HTML of the page.-->
   <script src="https://moderate.cleantalk.org/ct-bot-detector-wrapper.js"></script>
</head>
<body>
   <form method="post" action="your_form_handler_script">
      <label for="user_name">User name</label>
      <label for="user_email">User email</label>
      <input type="text" name="user_name" id="search_field" /> <br />
      <input type="text" name="user_email" id="search_field" /> <br />
      <input type="submit" />
   </form>
</body>
</html>

When you got added the script, the form will be updated with hidden event_token field after the script loaded. This field value you should transfer to VB Script

Once the token is provided in the API request, the VB Script will make the API takes in count the frontend data.

Make note, that data provided on event_token have the higher priority than the data set by optional VB Script setters.

New Customization Options for Contacts Encoder Phrases in CleanTalk Anti-Spam
We’re excited to introduce a new feature in CleanTalk’s Anti-Spam plugin:
custom phrase settings for the Contacts Encoder.

Starting with version 6.52, you can now easily customize the default messages shown during the contact data encoding and decoding process — making the user experience better aligned with your website’s tone and style.

You can edit the following three phrases:
- “The magic is on the way, please wait for a few seconds!”
  Shown while decoding is in progress
- “The original one is”
  Shown right before revealing the contact information
- “Decoding the contact data, let us a few seconds to finish.”
  Displayed while processing contact decryption
These options are available in the plugin’s Contacts Encoder settings, under the Data Processing tab.

Make your contact protection both invisible to bots and friendly to users — now in your own words.

How It Works

You can customize the Contacts Encoder messages by adding a few simple code snippets to your site’s functions.php file.
For step-by-step instructions, check the guide [here].

This update helps you create a more personalized and user-friendly experience — while still protecting your contact data from bots and crawlers.

WordPress Plugin to Stop Spam in Reviews: Real Protection for Site Reviews
Review forms are among the most vulnerable parts of any website. That’s exactly why, in order to protect them effectively, using a WordPress plugin to stop spam in reviews is not just helpful — it’s essential. If you’re using the Site Reviews plugin for WordPress, you’ve likely seen fake reviews, spammy links, or even automated bots flooding your site.

You just spent 30 minutes deleting 17 fake reviews. And yet, tomorrow, there will likely be 25 more. As a result, it becomes a familiar — and frustrating — cycle that wastes time and drains energy.

Why You Need Spam Protection for Site Reviews in WordPress

Manual moderation quickly becomes unmanageable. Likewise, simply hiding forms doesn’t solve the problem. In both cases, the real issue remains untouched — automated spam submissions from bots and crawlers that specifically target testimonial and review forms.

If you’re searching for a way to stop fake reviews in WordPress, a dedicated anti-spam plugin is the most reliable option.

How CleanTalk Works to Stop Review Spam in WordPress

CleanTalk Anti-Spam provides direct integration with the Site Reviews plugin. It filters every form submission before it’s published, blocking anything suspicious automatically — without affecting real users.

Here’s how CleanTalk helps:

One plugin for all WordPress forms
In addition to reviews, CleanTalk also protects comments, contact forms, login forms, and registration pages — offering full-site anti-spam coverage.

Seamless integration with Site Reviews plugin
Better yet, CleanTalk automatically detects review forms and works right out of the box — no configuration required.

Stops spam before it hits the WordPress dashboard
In fact, you won’t even see the spam. CleanTalk blocks suspicious submissions in real time, keeping your admin panel clean and distraction-free.

Cloud-based filtering with zero impact on site speed
Unlike many plugins, CleanTalk does all the processing in the cloud. Your WordPress site stays lightning fast.

Invisible anti-spam protection for users
As a result, users won’t encounter any interruptions or confusing fields. Instead, the form remains fast, simple, and easy to complete.

Compatible with any review form setup
Whether you use shortcodes, modal popups, or custom implementations, CleanTalk has you covered.

Detailed spam logs and activity reports
Easily review what was blocked and why — great for troubleshooting or analytics.

Real Results: Preventing Fake WordPress Reviews

For example, on a WordPress site with over 300 monthly reviews, CleanTalk blocked 87 fake submissions in just one week — all without a single false positive.

Behind the scenes, the plugin filtered spammy review attempts using IP blacklists, content analysis, and behavioral patterns. Meanwhile, real users experienced no interruptions whatsoever.

How to Get Started with CleanTalk Anti-Spam Plugin
1. Go to your WordPress admin → Plugins → Add New.
site reviews spam for wordpress 1 1
1. Search for “Spam protection, Anti-Spam, FireWall by CleanTalk.”
