Under copyright laws of many countries, anyone with the intent to remix an existing work is liable for lawsuit because the laws protect the intellectual property of the work. However, current copyright laws are proving to be ineffective at preventing sampling of content. On the other hand, fair-use does not address a wide enough range of use-cases and its borders are not well established and defined, making usage under "fair use" legally risky. Lessig argues that there needs to be a change in the current state of copyright laws to legalize remix culture, especially for fair-use cases. He states that "outdated copyright laws have turned our children into criminals." One proposition is to adopt the system of citation used with book references. The artist would cite the intellectual property she sampled which would give the original creator the credit, as is common with literature references. As tools for doing so Lawrence Lessig proposed the Creative Commons licenses which demand for instance Attribution without restricting the general use of a creative work. One step further is the Free content movement, which proposes that creative content should be released under free licenses. The Copyright reform movement tries to tackle the problem by cutting for instance the excessively long copyright terms, as it was debated by scholar Rufus Pollock.
