Truthfully, I'd bet there would be a market for them.
Look at those pitiful creatures they call "twisty cats" They are deliberately bred with horrible birth defects and crippling, and people pay outrageous sums for them because it's a novelty, they can have a cat the neighbors don't have.
Personally, I think it is disgusting and wrong to purposefully breed a deformed or impaired animal just to have a novelty pet. A spider ball with extremely severe wobble would be just that, a novelty. Something to show off to people, " Hey, look at my cool snake, it's all messed up!"
After a while, when the reality of how hard it would be to properly care for such an animal sets in, they'll loose all interest in it. Since there would be minimal market for a snake like that, it would likely then either be neglected to death, or even released to die in the wild.
Why do you think people do that with giant pythons? They want a novelty pet, something with shock value. When the snake gets too big to control, it's left to die of neglect or released and left to fend for itself. That is why you see so many media clips about " huge dangerous snakes" on the loose.
So yes, while I could see some people buying a spider with a severe wobble for the novelty, I firmly believe it is a bad idea, and to perpetuate people buying novelty animals they can't properly care for makes you irresponsible.
