There's no way to mask it, apart from use another one whilst using his tool. On CEX you can change your id pretty much instantly from your PC and keep a note of your current one. IMO I don't give a crap about my id, when its banned I get another one there's a plentiful supply of them

i highly doubt raw dog has a cid stealer in his tool, if there was the thread would be closed, its usually noobs getting console banned because they don't know how to safely play online with cfw.
