If you do massive link spam, not matter what others will telll you, that site will get in sandbox, after it let the sandbox, it will rank better. In general, you do not have to do sb direct to your money site, but if you do not have any trouble to be in sandbox for a time ( usually it is 2 months ) , it is ok.
I even did it with a youtube video that I upload it, it was ranking good, I did a blast for 1 weeks ( may be no more than more than 2000 autoaproved back links ) and that link went to sandbox for a month, then, it ranked better than before the sandbox.
test by yourself.
