But focusing on the topic of this thread...
Basically, the proposal was about a new building, a "Shrine of Plunder" (or like Graviton said, Shrine of Mafia), which can be plundered by an attacker when motivated so that they are not tempted to take anything else. Is that correct?
This is why you should try to have as many event buildings as possible, so that when you do get plundered, you have a lot more still left. Oh, your Sleigh Builder was plundered when it was in a 1-day production? Big deal, I have another one, a Mad Scientist's Lab, and many goods buildings (including GBs) and production buildings.
And probably the most common tip of them all, collect on time!
