I think his biggest problem nowadaysis that the whole 'anonymous' thing no longer works. It means that you can't take him too seriously as an artist because you don't see him discussing his work (and illegal street art seems an odd area for a wealthy middle aged man to work in), and you no longer think he is an outsider because he's worked with some really big brands.
