I had always assumed that posting the link to the original article and stating "from xxxxx" was sufficient to give credit to the owner, but now it seems that "permission" is required from some sources..?
So I suppose that's 2 questions..
1. Is there a universal way to properly credit the original material copyright holder(s) and avoid any chance infringement? or can we only post a link and refer to the original material only, without copy/paste/quoting it?
2. If copyright holders cannot universally be satisfied by a generic cross-posting "credit", as some may reserve all rights, how do we tell which is which.?
