Personally I think Franco is just embarrassed to admit that they got the idea of his character from Riff Raff so they looked for a more "legit/serious" rapper who looked similar (Dangeruss) and now claim that he was the inspiration.
I mean even the director of the movie did a photo shoot with Riff Raff last year. He was 100% the inspiration behind Franco's character. Anyone who has seen several of Riff Raff's videos will be able to see the countless similarities between the two. From the clothes, the accent, and even damn near word for word of what he has said in the past, etc..
