I don't want to get into a pissing match about it, but that particular source has been very helpful to many people on another forum dedicated specifically to rainbow boas, and whether he originated that care sheet or got it from somewhere else, I'd still argue that it's valid, as he does keep and breed a large number of BRBs successfully, producing many beautiful animals in the process. Whether you like or dislike him personally for your own reasons doesn't negate the usefulness or validity of the information he has provided.
