I strongly disagree with this.
Bloods are not a species I would recommend to a beginner. More specific husbandry requirements, typically more cranky personality that you have to handle much differently to gain their trust, and an animal that easily is 15-25 pounds of power as an adult is not for everybody.
I know many experienced keepers who have kept bloods for a while, including myself, and they are not for everybody. I would recommend a carpet over a blood any day as far as a more intermediate difficulty snake.
