Why does only a direct link work?

Question

Joomla

CMS joomla 3.0
There is a link:
When you copy it to the browser's address bar, it works correctly. If you insert it, for example, in VK or google + or even here, the transition does not occur
Where to dig?

Answer 1

Is it a new kind of advertising? )))
The site has a redirect to the part of the referrer.. Why this is done, of course, is not clear..
It is logical that if it comes from the address bar, then there is no redirect, since there is no referrer.
