Not everybody is in DMCA jurisdiction. Maximum liability in Canada is something like $5000, which makes it uneconomical for a copyright owner to actually send a lawyer to court to litigate against a person who wants to defend themselves.

I'm not sure what you are saying, no one implied everyone was in the reach of HBO. The parent was saying HBO was going to go after torrenters in the future, but they have been doing it for years.

I guess what I'm saying is that inevitably in these sorts of discussions, about legal repercussions, the assumption is that the torrenters are physically located in the US 50 states.

No one assumed that here, the parent said HBO would go after torrenters in the future and they have been for a long time already.

In fact, HBO is perhaps the most aggressive monitoring/enforcement of all content-creators. They are very, very proactive.
