TOPIC: Stealing from my City

On server #13A (Small CityBuilder) there is a person named Elakod who is stealing from my city. i placed my trains and had the system running then i see this 3 platform station built with trains stealing my passengers and mail and then nothing more then 5 minutes later hes putting busses and trucks in it aswell!! Im sitting watching him steal all of my mail and passengers as i struggle in my town. i asked him about three times very nicely to stop and he has just ignored me. please do something about this person. Thank you for your time.
