Of course there's a lot of overlap when it comes to porn and copyright infringement. The entire business model of many porn aggregation sites seems to be to steal videos from subscription services and offer them for free, although the relationship between such sites is more complicated than you might think.

The ACL can't simply point out that YouPorn has lifted videos from other sites and therefore convince a judge that YouPorn should be blocked. The complaint has to come from the copyright holder, or from an Australian company that has licensed the content – although just one infringement is enough to lodge a request to have a site blocked.

To have YouPorn blocked, the ACL would need to either own or license something that's on the site – which is perhaps a bridge too far in their fight against porn. Depending on how it was done, such tactics might be viewed by the courts as an abuse of process and knocked back – one of the advantages of having this process overseen by a judge rather than backroom bureaucrats.

There's another more practical loophole for anti-porn crusaders to target; music. You can be sure if you trawled through any porn aggregation site that you'd find clips using copyrighted music without permission. If you found an artist or music label happy to play ball, you might be able to have porn sites blocked that way – assuming the judge signed off on it. Alternatively the ACL could license the Australian rights to "bow chicka wow wow" and hope to wipe out 1970s porn overnight.

You can be sure that every lobby group in Australia which wants something banned is sitting around brainstorming ideas on how to turn the new anti-piracy rules to their advantage. Rather than looking for loopholes, the ACL will more likely just bide its time and wait for the government to declare the anti-piracy laws a success.
