The United States case of Drauglis v. Kappa Map Group is one that has raised eyebrows in the Creative Commons community. Without going into much detail on the case there are various lessons that can be drawn from the case for licensors and licensees.
Always read the terms and conditions and know what the risks are when you are uploading your material on to Social Media sites as well as general Websites. As much as CC licenses set out to protect copyrights these licenses may be narrow in the rights they protect (as seen from the ruling of Drauglis)
Hence it is vital to understand the length of conditions and terms that your license covers.
CC rarely ever finds itself in a lawsuit and with good reason to. It is key for users to use the licenses available them with caution and a substantial amount of knowledge about the resources available to them.
