Expert server but is training server

Today I was doing a regular flight at (EGBB)Birmingham.There was a inappropriate player on the expert.Scandinavian 112 Super was taxing through grass to pass me.This is not allow on expert server except casual or training.Also the word super was in his call sign.He didn’t have a fight plan and did Vfr.He’s plane didn’t weight to “Super”.This player was holding short runway 15 before the line.There’s some of the photo and to show his name.He got report but he still playing on the server.

He got ghosted. All is good now. End of story.
