SignShop Removal

Our friend who once played with us set up a few SignShops, but left without removing the shops. Is there a way we can get an admin or anyone who can remove them to, well you know, remove them?

Pictures:

There are 8 shops total.

We need these shops to be removed for a new building to be put in its place...

Thanks for reading, if anyone bothers to anyway... Tell me if you need anything else in this post
