I just deleted a comment on someone elses wall, WTF?

OK, I get it, but I dont get it. Someone installed an app, I happened to check their wall because I changed images and I wanted to see how it looked. When I went to their wall, the person had commented that it is not what it seems, so dont do it, something to that effect. For whatever reason I clicked on the X to delete it figuring it would ask if it was spam or not, which of course I would then ignore, instead it just let me delete it. I logged in another account and checked the wall, it is gone. It could just not be showing for my IP, but I doubt it. So, I deleted her comment, yes, it was on a post by an app I am admin of, but still, I should not be allowed to delete a comment on her wall.

EDIT: Could it have to do with granting permission for 1 hour to the app, and since I am admin of the app, I could do it? It was within an hour.

LMAO I think you have special powers!!!!
Yes the app did it. You may want to change the admin to 15 minutes.
