Anti-spam, Spam protection, ReCaptcha for all forms and GDPR-compliant


Blocked hundreds of spam WooCommerce orders, and the plugin continues to be actively monitored and improved. I'm sure it will continue to get even better. Great work.


Excellent


The developer is really motivated to get this plugin going. Nice guy.



And the plugin helps catching spam without violating GDPR. Great for german or EU-sites.



Thanks a lot for this plugin.


Works like a charm and great developer-support

OOPSpam Anti-Spam: Spam Protection for WordPress Forms & Comments (No CAPTCHA)

This is a great plugin with a very responsive and knowledgable support team.

I emailed them yesterday with a kind of obscure WooCommerce feature request and they had a fix deployed within 12 hours.

Yes, it's a paid service if your site has any kind of volume at all, but it's extremely effective and fully built for privacy and GDPR compliant. We're trying to de-G00glify everything for our clients so their websites are not tracking users every move and implementing this service is part of our (slow and tedious) move in that direction. 

Pricing is perfect for agencies as they do tiers by actual # of API calls and no limit on the number of sites you can install this on. Most competitors we were looking at had per-site license structures that were not going to work for us.

Works well for default comment fields, WPForms and WooCommerce. Has some other integrations but those are the ones we tried.

If you have any doubts, just go back into your logs of spam that slipped through reCAPTCHA and Akismet and a honeypot... pick a message and enter the data on the app.oopspam.com dashboard you can edit the test data right there and it will show you what spam score their system would give that message.

Great Service
