Yes, I'm having the same problem, Recaptcha is obviously on a blocked domain, based on my settings. But I've done internet searching and haven't found anything to indicate which specific domain Recaptcha uses or routes through. The blocked domain stats don't include any domain using "Recaptcha" or anything similar. The only connection that may be helpful is that Recaptcha is owned by Google, and I have www.google.com blocked in my settings (but not other google domains). Unfortunately, if Recaptcha does route through the google.com domain and not a subdomain, the blocked domain stats won't help.
"There are certainly instructions"
That seems to not be the case, since I've searched several times and can't find any.
"...you must search the internet to find them"
I have searched but find nothing helpful. The first 2 pages of search results are addressed to adding Recaptcha to your website, which obviously isn't helpful to me.
Perhaps you could offer more specifics on these instructions you're referring to?
