 Free culture has become a relative success, the free Creative Commons licenses are now widely used -- e.g. **[Wikipedia](wikipedia.md) is part of free** culture under the [CC-BY-SA](cc_by_sa.md) license and its sister project [Wikimedia Commons](wm_commons.md) hosts over 80 million free cultural works! There are famous promoters of free culture such as [Nina Paley](nina_paley.md), webcomics, books, songs etc. In development of libre [games](game.md) free cultural licenses are used (alongside free software licenses) to liberate the game assets -- e.g. the [Freedoom](freedoom.md) project creates free culture content replacement for the game [Doom](doom.md). There are whole communities such as [opengameart](oga.md) or Blendswap for sharing free art, even sites with completely public domain stock photos, vector images, music and many other things. Many scientists release their data to public domain under [CC0](cc0.md). And of course, [LRS](lrs.md) highly advocated free culture, specifically [public domain](public_domain.md) under [CC0](cc0.md).
 
-**BEWARE of fake free culture**: there are many resources that look like or even call themselves "free culture" despite not adhering to its rules. This may be by intention or not, some people just don't know too much about the topic -- a common mistake is to think that all Creative Commons licenses are free culture -- again, this is NOT the case (the NC and ND ones are not). Some think that "free" just means "gratis" -- this is not the case (free means freedom, i.e. respecting the above mentioned criteria of free cultural works). Many people don't know the rules of copyright and think that they can e.g. create a remix of some non-free pop song and license it under CC-BY-SA -- they CANNOT, they are making a derivative work of a non-free work and so cannot license it. Some people use licenses without knowing what they mean, e.g. many use CC0 and then ask for their work to not be used commercially -- this can't be done, CC0 specifically allows any commercial use. Some try to make their own "licenses" by e.g. stating "do whatever you want with my work" instead of using a proper waiver like CC0 -- this is with high probability legally unsafe and invalid, it is unfortunately not so easy to waive one's copyright -- DO use the existing licenses. Educate yourself and if you're unsure, ask away in the community, people are glad to give advice.
