This is old news, they keep saying this but never act on it. Part of the reason being the whole shabang is untraceable.
Tip : get a B2 account if its available in your city and stick to it. Back when I was trading actively I used my B2 account extensively. Will not go into the details of the entire turnover but it was a lot. And this was after RBI made their rules more stringent in (and after) 2008.
