Plagiarize my effort and in the process capture the fake/non existent streets I -added- to the map to show that you were plagiarizing my work? Then absolutely I have a case against you.
Come up with the same lyrics for a song as I do based on listening to it? Fine.
Cutting and pasting my content, including unnecessary embedded Unicode spaces used to watermark my content, my transcription (see my other comment on this), absolutely problematic and actionable.
