You already know <a href="https://wordpress.org/plugins/give/" rel="ugc">GiveWP</a> is one of the highest rated, most downloaded, and best supported donation plugins for WordPress — so do spammers and credit card thieves. That’s why we created reCAPTCHA for Give.
Donation forms are a favorite target for spam bots and fraudsters looking to test stolen credit card numbers. It can become a serious issue, affecting site performance & lead to your payment gateway suspending or even closing your account. That’s where <a href="https://www.google.com/recaptcha/about/" rel="nofollow ugc">Google’s reCAPTCHA</a> comes in.
<h4>How reCAPTCHA works</h4>
reCAPTCHA uses an advanced risk analysis engine & adaptive challenges to keep malicious software from engaging in abusive activities on your site. Meanwhile, legitimate users will be able to login, make purchases, view pages, or create accounts and fake users will be blocked.

<h4>reCAPTCHA may not be the best option</h4>
reCAPTCHA may not be the best option for some sites. It could slow down the donation experience, look unsightly and may harm your donations more than benefit them. Luckily there’s a great alternative to reCAPTCHA that supports GiveWP donation forms, <a href="https://wordpress.org/plugins/zero-spam/" rel="ugc">WordPress Zero Spam</a>.
If you’re still receiving high amounts of spam and fraudulent transactions, reCAPTCHA is a great option as your last line of defense.

Identibyte for Contact Forms 7 will detect and block signups and 
submissions from disposable email addresses in your forms. Saving 
resources for real users allows you to spend time and money on the 
users that need it most.
Setting up is easy:
<ol>
<li>Install the Identibyte for Contact Form 7 plugin.</li>
<li>Enable Identibyte validation on any Contact Form 7 email tag.</li>
</ol>
You can use Identibyte for Contact Form 7 completely free without an 
Identibyte account and make 20 “checks” per hour. If you need more 
checks, you just need to sign up for Identibyte and create a free or 
upgraded API token. Learn more below.
<h4>How it works</h4>
When you have Identibyte for Contact Form 7 installed and activated, 
Identibyte will validate the <code>[email]</code> tags in your Contact Form 7 
forms. All you need to do is add the <code>identibyte:true</code> option to any 
 [email] or <code>[email*]</code> tag.
For example, like this: <code>[email* your-email identibyte:true]</code>
When the form is submitted, Identibyte will check if the email is a 
disposable email address. Identibyte has custom technology and 
processes for discovering and keeping a highly up-to-date blacklist of 
disposable email providers.
And that’s it! Now your signup forms are intelligent and can detect 
and block users signing up or submitting information that have a 
disposable email address.

<h4>Adding an API token</h4>
If you need to make more than 20 API requests an hour, you can 
[sign up for an Identibyte account]((https://identibyte.com/signup) 
and <a href="https://identibyte.com/dashboard/tokens" rel="nofollow ugc">create an API token</a>. 
Once you have a token, enter it the Identibyte plugin’s admin settings 
page.
After the 20 checks per hour are exhausted, if you haven’t entered an 
API token, Identibyte will be bypassed and will not fail the form 
submission validation.
<h4>What you need to know</h4>
Identibyte for Contact Form 7 relies on making HTTP requests to the 
<a href="https://identibyte.com" rel="nofollow ugc">Identibyte API</a>. API calls are made when a 
Contact Form 7 form is submitted, for every field that has the 
 identibyte:true option.
Identibyte is an external service and has it’s own 
<a href="https://identibyte.com/termsofservice" rel="nofollow ugc">Terms of Service</a> and 
<a href="https://identibyte.com/privacypolicy" rel="nofollow ugc">Privacy Policy</a>, which you can 
review at those links.
<h4>Support</h4>

<a href="https://identibyte.com" rel="nofollow ugc">Identibyte website</a> and 
<a href="https://identibyte.com/#docs" rel="nofollow ugc">API documentation</a> for helpful
