@A Link In Time would you count Storm's posts as a this game day's claim, or would you brush it off as a joke?
It's up to the discretion of the player with a power role if the benefits outweigh the disadvantages. They should be at least given the option, and Storm taking that away definitely doesn't help their case.
While I don't see this move scummy, per se, because it brings a lot of attention to him, I don't like it, and Storm, you really need to read the rules and role claim, even joke claim, a lot less. It helps no one.
Also, this game is going to force me to rewatch Book 3
