Okay, 3 questions here: 1. Why does this pool exist? 2. Why does the name not contain 'Fubotty'? 3. Why does this pool exist?
Because Vincentglen Aquiatan created it (today) and all that user's uploads are Fubuki pics, half of which are nude filters that are not going to pass the queue.
Besides that, I presume it's because Aquiatan hasn't been around long enough to see terms like "Fubooty".
