protection

Hello, I would like to know how does the sponge permission works. If i give someone permission in my region, will the person be able to destroy my sponge? Also, will this person be able to use the sponge commands? Like adding someone new in the region, or hide the sponge. Thank you!

Hi eveyone, I was wondering if there is another way to acquire protection sponges? If so how do you go about acquiring them. Thanks for everyone's help.
