fast-mail-bomber VS recaptcha

I know Google has a ReCAPTCHA service, and I think it’s free up to scales I would probably never use up. Still, I’d prefer something than can be self hosted so is totally free. And where you don't have to register your domain with a 3rd party, you can just use it on any domain.

The traditional way of using "I am not a robot" Recpatcha seems to be with a

## Step 1: Obtaining reCAPTCHA Keys Go to the Google reCAPTCHA website (https://www.google.com/recaptcha) and sign in with your Google account. Click the + sign and fill in the details as follows:

Note that 'script-src-elem' was not explicitly set, so 'script-src' is used as a fallback.
