I had a sort of similar incident happen with the youtuber Siraj Raval who was ripping off people's original projects (without attribution) and making videos about them -- and spun a career out of it.
It took many attempts to get him to attribute my project (in accordance with its license) although he was caught repeating this type of behavior later on.
