And I'm not required to - I'm required to send DMCA when I have a belief in good faith that content is mine. Screenshot + download link = good faith belief.

File names do not matter at all. Since a very long time most of the uploaders use random file names to avoid spiders or sometimes to even hide the real meaning of their files from file lockers - when they do not allow porn for example. It didn't change anything in the scheme above. No billing company is going to say they're not going to put a strike on record because the file name is 16763mna.rar and not stolen_video_from_your_program.wmv.
