I was wondering if it is legal to use sponges under my city? My city is in the middle of the ocean and I would like to go under the entire thing and remove all the water. I know in the rules it says not to grief with them, and this I guess could be considered griefing if it was done in the wild. And I also know that griefing with water after you donated for it, can get it taken away. So yea, am I allowed to do this to my own city? ( I do understand there will be a gigantic crater under it, lol)

 

Thanks all, just covering my tracks. :D
