It is apparent that your son and his twin are determined to show that they are making the decisions regardless of your boundaries. I am not sure what having him log in here will do as the twins appear determined to do what they are going to do. As well that could escalate the battle of wills for I'm certain there are websites promoting your sons's behaviours. I am going to repeat that I think you should find a counselor to help you sort through this, the loss of your wife and help you set boundaries so you can move this family forward.
