Well, a) I have a hard time believing that many people open new accounts for stable slots, and b) thats not an acceptable excuse anyway.More accounts maybe? Is possible, non?
If money grab really were the case they could just sell stable upgrades in the code store.
I personally think its either something weird in the code wont allow people to have 100 pets, or they just don't want people to have a lot of pets, for some unspoken and as far as I or anyone else has ever deduced nonsensical, reason.
Or they simply don't think it's important.
I would love to know the actual reason.
