I know people who have done this. I ask them after their exams whether they used their notes, the reply is almost ALWAYS, "nope, didn't use them at all".. I guess all the scamming/cheating techniques were enough for them too pass with out looking it up.
To me, seems like a lot of RISK for the return if you ask me.
Proud to say that I got through my 17 exams without cheating,
go_soaring! instead
P.s. heard of one extreme case that someone reduced all of a well knowns set of notes into A5 and stuck them into their AIP!! Bit of a myth, but like anything in this crazy world - if you can think of it, it's probably been done!
