I'm pretty uneasy about legal action against the subscribers themselves. If you can prove intent, maybe? But I'd argue many or even most don't realize they're doing anything illegal.
These IPTV companies, in my experience, never advertise that it's illegal. It's just give us money for a lot of TV channels, just like a cable company does.
People refer to them as “dodgy boxes”. They know it’s illegal and no one cares.
Everyone in the country knows this and either has one or a family member has one
I'm not familiar with how these IPTV companies market their services, but I'm extremely skeptical of the notion that people don't realize they're buying something illegal when they're paying a small percentage of what the services themselves would cost.
It's like those folks that sold bootleg DVDs out of their trenchcoats in Manhattan - the defense of "gosh, I never knew buying a just-released-in-theaters Hollywood blockbuster for $5 by some dude on the side of Broadway was illegal" was never going to fly.
