As far as what Fuji kun told me, I was permitted to share that stuff with Kobe before because:
1- Kobe is my GA target
2- I was in a exclusive, "special" chat with him, unrelated to the shop ability. Because I targeted his role with an ability to know who the player was.
Aside from this exception, what's talked in the Shōten, stays in the shōten.
Which makes sense for balance purposes.
