InfoLinks is not a scam. Could be a number of things gone wrong. But the best move would be to call them, or to drop them a line.
They pay... on time. Check to see if you met the payment threshold... and if you completed all required tax forms.
@Forumdirectory : I am also in trouble. I haven't received any payments for November 2009. They were paying in time, around 31st of every month. This time my account shows that payment issued on 31st. However the fund is not yet available in my Paypal account.
