First, I need to verify if this is a real video ID. I can check by looking up FC2's content ID structure. FC2's content IDs typically follow formats like FC2-PPV-XXXXXXX or similar, where the numbers vary. The given ID "fc2ppv1780072" follows this pattern. However, FC2 also uses different formats for their paid per view (PPV) content, so "fc2ppv1780072" could be a specific content ID.
