Need a spam-resistant 'Contact Us' form plugin

I got a russian spam on my contact page and need a Rapidweaver plugin /Contact Us plugin that either has good spam-killer tech or some sort of captcha/human test mechanism.
Any recommendations? What are you using for your site?

Doobox Contact Form - it uses the honeypot method so I do not have any spam on my sites… https://doobox.co.uk

There’s also https://rwextras.com/compactform/ which uses the same method.

And the free Formulate stack if you’re using one of my themes.

Thanks for the link Will! I didn’t realize you had some theme dependent stacks on the themes site!

Everyone has given you stacks. The post asked for plugins, so you might have a look at FormLoom 3, it’s a plug-in and also can be displayed on a stacks page. It’s very secure and has reCAPTCHA Support.

and Formloom 4 is on it’s way promising some pretty nice new features

Plugin, stack…doesn’t matter. Sorry I didn’t clarify
