Yup, I think this may be new but it has been added to it:
reCaptcha module for Contact Form 7
I really wish that the developer added the module in the plugin distribution because those of us who use Contact Form 7 have to manually re-upload the module every time he makes a new version
I actually downloaded the module again today, the website asks for a donation. I’m guessing he’s hoping to get a bit more this way, however, as you say it can be a bit tedious.
Why is this not available anymore?
It worked great for me.
I don’t know why it’s not available any more, but I have asked the developer on twitter (https://twitter.com/takayukister).
I’m waiting for a response. But this add-on is a must for Contact Form 7.
I wonder if donations do have a part to play in its disappearance…

Takayuki said that it’ll be back again at some point… 4 months ago
