Technically, it would be safe -- as long your brother has his own internet connection ( that is, not using a shared Wi-Fi connection ) -- using another device shouldn't be an issue; though, just to be on the safe side, and if you still feel worried about the issues that may come from it, you can inform the Staff by submitting a HelpDesk Ticket and tell them of the matter
