If you think disabling dualbox will have any actual impact on dualboxing on a russian server, you are cute. They open more VBox/vmware machines than you can imagine. But for people who have no clue how it works it'll be a problem. So I would leaveit as it is. If you played other retail classics you know dualbox is part of the game. It was different before, yes. There were no looped macros which made it harder compared to today, but still, I wouldnt block it.
Also first lines of your post, Im touched.
