This is the first time for some weeks there have been more than just a few spam posts visible. They all came in a short time span shortly before your post, and were all deleted shortly afterwards.
The usage policy for this bb was set by the Club BoD.
It requires you to use a valid email address.
Otherwise, if anyone replies to your post, it creates indefinite bounce back messages which ultimately can cause the server to crash, bringing down the other bb's as well.
