Sub thread hidden?

To whom it may concern. 

I recently tried to post something on my subpage, and realized that I can view my sub thread, but nobody else. 

I have tried looking in the API, and the entire thing seems to be missing. https://www.khanacademy.org/api/internal/discussions/scratchpad/6652809926492160/comments?qa_expand_key=ag5zfmtoYW4tYWNhZGVteXJpCxIIVXNlckRhdGEiRnVzZXJfaWRfa2V5X2h0dHA6Ly9pZC5raGFuYWNhZGVteS5vcmcvMWU1YTE0YmJmYTliNGZiNWIwODY3MTU1OGI0NjQ1MjYMCxIIRmVlZGJhY2sYgIC1k4Kp9QsM&format=pretty 

Does anybody know what's going on? I have gotten no messages from guardians saying that it has been hidden for any particular reason. For reference, my subpage is here:
