For me my Website(A) works as a Platform for Users to share Videos, Images and Links from Other Websites, Lets take for example Youtube
of my Website copied an Embed Code of Illegal Copyrighted Video Hosted on Youtube.
User(A) logged to my Website and used this Embed Code to show the Video.
so the steps are
Illegal 3rd-Party Embed Code Copyrighted (YT) Video
-Uploaded By-> User(YT)
-Taken By-> User(A)
-Shared at-> Website(A).
Does my Website(A) takes any responsibiltiy of that 3rd-Party content?
I didn't host the Content or anything on my Website, It is hosted by Youtube, And Youtube allows me to take Embeded Codes of their Videos to share it on my Website.
