For me the most obvious issue with it is that, unlike on a reputable render farm, the confidentiality of renders isn't in any way guaranteed, which is a full stop deal breaker for most professional work. Sure this might work for hobby projects but even on my hobby projects I want to retain control of my own IP. If I used you for professional work I would be breaking some of the terms of pretty much every contract I've ever been asked to sign as a creative. Not sure how you get around that unless you run blender in a black box process.
