If 1,000 people made videos about Islam and the truth about its origins, would they have time to track all of them down? How much would it cost to make a video? Sunlight is the best disinfectant.
After seeing the video in question I think about $100 bucks. Most of the money on this particular video was used for very bad makeup.
The "movie" in question is pretty bad. So bad it's funny. But there is nothing illegal about making a bad movie and the government has no business figuring out who made it and why.
