Link Preview contains wrong name for the site. Should be "Pomponik" not Pomponik.pl. You can clearly see that it's how they call themselves in many places:
"Przejdź do strony głównej serwisu Pomponik na INTERIA.PL" which means:
"Go to the front page of Pomponik, on INTERIA.pl"

Also, at the bottom of many posts, they are being put as the source of information as well, and they are called "pomponik" there.
