Yesterday, a user named Jake Tinsley made a sandbox page on the main wiki. I told him that this was not the place for it, and several other users pointed out the proper area to create a sandbox. He apologized and sought assistance in how to create a sandbox.
Today, he created another sandbox on the main wiki. Since he apparently ignored/forgot/disregarded what he had been told, I'm recommending some disciplinary action.
