Thanks for the report. Seems the domain age check doesn't work at all anymore.
Created a webservice to get age data, test: https://pebosi.net/api/domainage.php?url=piwik.org (will return created timestamp and age of domain in seconds)
See attached patch for integration.
Added ability to get age from ".de" Domains
This is Piwik, an open source web analytics software. I love it because it is open source and I have a full control over it. This is why I got rid of Google Analytics after I found Piwik. And I don't want no closed source APIs in it which are not under my control. I hate when people try to make me dependent on their service.
pebosi, make this script open source to make Piwik more independent of third-party APIs.
