No support. I realize it might seem cruel to buy a pet, scan it, and release it, but once someone owns a pet, they're free to do whatever they want with it. I can't say I like the behavior, but I see no reason to block people from releasing pets. A lot of people scan most of their pets, whether they bought it from someone, or it was already theirs. Then there would be very few pets in the forest.
The whole point of the forest is to release unwanted creatu for others to adopt. Adoption agencies help out with this by having a person take care of a pet, but there's barely any difference. This is the system's way of allowing people to send their pets on. The forest is there for unwanted pets to find homes, and not all people will feel comfortable with an adoption agency because it's user-ba[injection]sed, and not part of the Res system. What a user does with a pet is entirely up to them.
