Also worth mentioning that the whole site was not blacklisted, only the page about pot consumption methods was banned, but the fact that the ISPs need DPI (Deep Packet Inspection) for banning just one page from the whole site (which they don't have implemented) they were just banning the whole site.
Also worth mentioning that now some lawmakers consider introducing new laws to outlaw "anonymizers" like web proxies or networks like Tor and I2P, because they help people to route around the law. Don't they understand that it is not technically possible? People will just start using VPN.
