Without being confrontational, and please don't take offence - but:
a) As Aiglon says - why do you want to know; and
b) What business is it of yours?
If you want to know for a deeper reason (i.e you've been p***ed off by someone and refused a crossing or similar) then say so - don't pussy foot around.
If you're that desperate then do a search - that sort of thing has been asked over the previous 4-6 months.
Take BRL & CZ's comments and multiply them severalfold and you'll get the general PPRuNe opinion - there is no 'them' and 'us'.
