SarahTheRed Aurbierre: Intellectual property theft is far more personal than just stealing stuff like a like a lawnmower. It's more than just things; it's something you've created, but time and energy into, and invariably put pieces of your soul into. It's very personal, and very valuable. While it may be harder to track than physical objects, it still carries the same weight. Imagine what would happen to our society if we suddenly stopped creating art, or inventing technology.
Buying stuff seems the obvious answer to how to support content creators. However I think it goes further -- we also need to be aware of who creates what we wear and use. No, we don't have to be friends with everyone, but get to know their work, and recognize what makes it uniquely theirs, and why it has worth.
Faery Sola: I've never been stolen from, but I put so much of myself into what I do, I'd be devastated to find my work ripped. Education is the only way to stop it. Appealing to peoples common decency & making theft in general, wether it be of peoples work or of software, socially unacceptable in SL.
