This website is blocked by all major ISPs in Spain. Here, a few websites that are (or have been) used to distributed illegal content (mainly illegal multimedia content) get blocked.
There is few that you can do unless you use another domain, since these are normally court orders. VPNs should work fine, with some ISPs using a custom DNS may work (but not for all).
