I post offsite some pictures but i don't obtain the star points. How the sistem knows i'm posting outside the pictures?
Your ID is attached to each link you post.
Clicks must be made by other people (you can't click the link yourself.)
Also if a link stop sending clicks after 3 months, then the link update the image is removed. (but you keep the star points!)
If you would like me to check the links you posted, let me know the URL and I will check it out.
