reCaptcha not working on WordPress jetpack contact form

Any plugin has to say that it will work with JetPack, if it doesn’t, then it won’t. I already tried one and it won’t integrate with JetPack Contact form.

You can add a Captcha instead, instructions are here:
https://jetpack.com/tag/captcha/

The JetPack people already made a suggestion for reCaptcha over a year ago, so I hope it is in the works, but it has been a year already. Really, after all, captcha or recaptha is suppose to be standard today with all the security and SPAM concerns, one would think the Dev’s at JetPack would have incorporated it already.
