This might be a dumb question, but I've done it myself.
Did you remember to click the save button at the bottom of the settings?
This is the 3 month old, announcement, and absolutely NOT a game-play trailer.
This in no way is indicative of what, anything in the game actually looks like.
I really like this photo.
At a glance it's a simple touristic type composition. But the lighting is acceptional. The people in the foreground are interesting. I keep looking at it. It's just perfect.
I would expect so.
But this community is for pictures of actual animals (rabbits for example) not people in animal costumes. So I wouldn't expect rabbit people.
That would be up to the admin of your host instance. Hypothetically they can ban you for any, or even no reason. There are no software or rules preventing it.
So I would suggest making an account on the instance you want to post these photos to.
