I'm really just an onlooker to this, but . . . honestly, nobody ever said there had to be one art site that fit everyone's tastes, where everyone could agree on the rules and live in harmony. Perhaps that was the objective of Fur Affinity, but given that it's been described as "allowing people from the furry/anthro fandoms to upload art, music and stories regardless of rating", it doesn't sound like it.
No one site can be everything to everyone. Eventually, something has to give. I think this is why no decision could initially be made on banning people, even among the admins. There was an assumption that an agreement could be found between two mutually opposing views; that cub art should be allowed here, or that it should not.
Well, it turns out that it is. I believe this is because of the principle that is behind the site, and has been for as long as I've known it. I see this as "anything goes, as long as it's furry and legal for us to display". This is perhaps an oversimplification, but then I'm a simple norn.
Methods are available for those who want to remain here but don't want to see certain pieces of art. If this is not sufficient, then there are plenty of other places to go. Please don't go there in anger. But you should go, because to stay at a site when you don't agree with its principles is bad for everyone's happiness. We've had people find that they couldn't live with how WikiFur worked either. Life goes on, for all concerned.
Lastly, I don't think FA is going to get shut down over things people post here, given that the recent changes have been made with specific consideration of the applicable law. My understanding is that the vast majority of such cases focus around images appearing to be real people. People here are making drawings of imaginary furry people. The law recognizes a difference. Anyone suggesting otherwise, I want some of the cookies you're eating.
