Some potential problems with the General Data Protection Regulation (GDPR)

CommentBox  is a very nice extension and works as expected. Unfortunately some external requests are performed to sites such as 
    fonts.googleapis.com    fonts.gstatic.com    www.gravatar.com
This will cause some legal issue, particularly problems with the General Data Protection Regulation (GDPR). Therefore, it is problematic to activate this extension in your Joomla-App without notifying the user.
It would be fine, if you can explain some steps to prevent the requests to external sites. What is necessary to store the used google fonts on your local host?
Additionally you can see some request to www.gravatar.com to get some small pics as avatar. This should be stored locally as well.
Without this functionality, it is very risky to use this extension in the European countries.

Hi,
The requests to the site fonts.googleapis.com and fonts.gstatic.com were initiated by the another component. There were not caused by CommentBox!
Apologies for misleading you.
The request to site www.gravatar.com is caused by CommentBox and I found a workaround.
You need to change the following file 
administrator/components/com_commentbox/src/Helper/UserHelper.php

class UserHelper
{
public static function getAvatar($email)
{
//return 'https://www.gravatar.com/avatar/'.hash('sha256', strtolower(trim($email))).'?d=mp';
return '/images/avatar.jpg';
}
}
Comment out the one line and add another line. However, this is only a workaround that may no longer be available in the next update. Therefore it is appreciated to deliver a permanent solution.
