it has to do with how many posts you’ve made, but I don’t know the exact parameters, it seems like everyone starts out as a penguin until they hit four posts, then they move to turtle. I don’t know where wolf starts but I found someone with around 20 posts, then people were polar bear with 30ish posts and goblins in the 50’s. skeleton seems to be the highest but I only found people with under 200 posts, not sure if there’s a tier after that
so, something like this:
penguin 1-4 posts
turtle 5-10?
wolf 20’s?
polar bear 30’s?
goblin 50’s
skeleton 100’s
