Can’t they track the location of those who downloaded them via torrents? Isn’t it technically possible?
All MAC addresses are traceable, until you change it.
Yes, in the simplest case, with a 10 year old or a liberal that has no clue, they can track and id to the computer.
If someone has a little more sophistication, they can throw a few levels of obfuscation in to make it much more difficult and expensive.
If someone has access to network admin privileges, suddenly, YOU downloaded the original "Parent Trap". And they watch their stolen movie.
It's a morality and marketing issue. Technically, the sky is the limit for someone willing to spend the effort.
