Registration Validator 1 is GPL and free to download (and listed on JED as such): extensions.joomla.org/extensions/access-.../authentication/7319

Registration Validator 2 is GPL but only available for download to subscribers (and listed on JED as commercial): extensions.joomla.org/extensions/access-...authentication/10802

This is clearly stated on this site AND in the JED, but of course to realise this you actually need to be bothered to read the information.
