przeciez strona (bez logowania na konkretnego usera) nie rozpozna czy masz zmienne czy nie zmienne ip, ale moze miec zablokowany zakres do ktorego nalezy twoje ip. Z faq na tej stronie:
Maybe my address is blacklisted?
The site blocks addresses listed in the (former) PeerGuardian database, as well as addresses of banned users. This works at Apache/PHP level, it's just a script that blocks logins from those addresses. It should not stop you from reaching the site. In particular it does not block lower level protocols, you should be able to ping/traceroute the server even if your address is blacklisted. If you cannot then the reason for the problem lies elsewhere.
If somehow your address is indeed blocked in the PG database do not contact us about it, it is not our policy to open ad hoc exceptions. You should clear your IP with the database maintainers instead.
sprawdzales czy ping do tej strony idzie?
Edit:
sprawdz traceroute i napisz jaki efekt, bo na pinga nie odpowiadaja
