Umm what?

If it says "Building" on the sign it's a building sign if it says any thing else it's not. I'm not to sure how hard it is for you to define between the two but it seems simple enough for an average person. We currently have to literally spell out every aspect of how to raid because you guys can't differ what's wrong or right.

Building
building
BuILdING
buildIng
buildinG

^ all still says building! It might look stupid but it's all the same thing and anything that doesn't have them 8 letters and in the right order isn't a building sign.
