Hey! Sorry for the super late reply, but I was digging around a bit and found it all out!
Koma-inu was the person who bought the foxpond, as a gift for Starmax, so I'm guessing they just gave it back as they weren't interested in it anymore and just haven't deleted it from their toyhou.se, this trade should be all safe for you!
Edit: Actually, I sent Starmax a private message to check if they approved of this
