This may be unpopular opinion judging by responses so far, but I am personally against the breeding of spiders and I think it's right to ban them. Even with spiders that don't exhibit severe symptoms, we are only able to judge the effects of the wobble by behaviour we can observe and since (as far as I am aware) there have never been studies on if spiders have elevated stress levels and other relevant factors, and snakes are not very expressive, we can't know if they are suffering or not, and how much, if they are.
This aside, knowingly producing animals that may not be able to feed or move normally seems unfair to me. Even if it is just one out of many snakes that will experience symptoms that severe, that is still a living creature that was brought into the world to suffer needlessly by choice. And before anyone brings up this argument, yes, I feel the same way about dog and cat breeds that are known to have health-jeopardizing defects like pugs and Scottish folds, and about any other animals that are bred as pets despite known health problems.
With that said, I can also understand why people like spiders and find them desirable. They are beautiful. One of the first BP morphs I ever saw was a banana spider, and I think it is still one of the most beautiful BPs I've ever seen. I won't hold my opinions against anyone who owns spiders, but I would personally never get one or support breeding them.
