Forum:Someone has edited many important pages and left them completely void

As I said in the title I found that quite a few pages have been left without any information, pictures, or even actual things that go with a character. Just some stupid letters put together "srfrvberfgze" from the page Simon Blackquill or a "yolo" on Trucy Wright's page. All of this seemed to have happened in the last few hours. Please show to an Admin if possible.
