reCAPTCHA is one of many "free" systems that are seemingly helpful and innocent, but are actually part of the #Google data-collection ecosphere.
If you must use a particular system that integrates with reCAPTCHA or similar, please provide them feedback that you would like alternatives to Google services.
Users, choose to solicit sites that value your #privacy and user data.
