Unfortunately, no it does not. There are two basic methods for pirating things in Second Life.
The first is known as “copybotting.” Copybotting is a generic term for duplicating the precise appearance of an object without making a real copy. It’s called copybotting because it is often done with “bots”, or software that is running an avatar in an automated fashion rather than being controlled by a person. Copybotting works because in order for you to see anything on your screen, it has to be downloaded to your computer. All of the shapes, textures, sounds, animations, etc that you see are all stored on your computer once you’ve seen them. Copybots abuse this fact to recreate whatever you’ve seen because it already knows the precise shape, size, textures, etc of the object. There will likely never be a way to prevent this sort of theft. When an object is copybotted, it USUALLY changes “Creator” to whoever did the copying, but it doesn’t HAVE to. However, copybotting cannot copy scripts. If someone were to copybot my tables, they would end up with something that looked exactly like my games, but didn’t work at all because there are no scripts in it.
The second type of piracy comes from permission exploits. My older games are all transfer/no-copy, but there are bugs in Second Life that let people copy them anyway, as if they were really transfer/copy. When copied in this fashion, the copies retain the original creator (me) as well as all of the scripts that they contain. They are indistinguishable from a “legitimate” game because they tricked Second Life into making a copy of it, instead of recreating it themselves. This is what is happening to my games. I personally know of two “bugs” that can make this happen, both of them can done by accident as well as deliberately. There may also be other methods that I’m not aware of as well.
