They get you to import your Linked-In list for free, and then they pester you with e-mail telling you who you know that is a Naymz member (probably some non-paying enrollee sucked in by the initial P.R.).

Then they pester you too frequently with e-mail telling you of ‘views’ to your profile, but offer no clues about who it is, or whether it is an absolutely meaningless or garbage view, a view from another member from your Linked-In list or not. If you want to find out who it is… you got it, you have to give them a Credit Card number.

The first month is free, but they know too many people will end up making one or more payments for nothing but pestering e-mails in return.
