And this is my whole point.
Everyone knows the correct way to get copyrighted content from the internet. You use iTunes, or Amazon's MP3 service, or NetFlix, or Hulu, or any number of services. Everyone also knows that when you get a legal copy of a copyrighted work there will be a 'payment' or a 'subscription' involved.
Naive people (I choose not to use the pejorative 'stupid' in this case) should know that any downloading of a copyrighted work which doesn't involve a subscription, or a fee, is nearly always illegal. This sort of action might train them with this fact.
Can you share information which is CC licensed or out of copyright or public domain? Absolutely. And I don't believe Titan Media or anyone else would be successful in pursuing someone by 'tricking' them with a filename that would otherwise be legitimate.
They could certainly try to sue you but any lawyer could move for a dismissal based on the clients beleif that the material was what it said it was, and deleted it immediately when they discovered it was not. There is no way to prove any sort of intent to violate copyright that way. Look of the case of Tracy Lords and her underage pornos where the buyer wasn't liable for child porn because she had represented to the production company and the production company had represented to the customer that everyone in the production was of legal age.
So if this educates a few thousand people that trying to get free copies of copyrighted stuff over the Internet is illegal and to stop trying (that would the educating the naive part) then its a good thing.
