How so? Wanda is in the Magic Kingdom. There is no one in Spacerock, who would be able to send a thinkagram or has an eyebook. Gobwin Knob doesn't have sending hats as well. Sure they will notice, but they won't be able to inform anyone about it.
Besides, Parson was fully aware he won't be able to go back through Magic Kingdom once they conquare Spacerock - it would stop being a capitol anyway.
