Getting links from popular no-follow sites

[danni]

Popular site who lets people to create an account or add the individuals information where you can add a link.

Those sites may not help you rank in the SERP's because they provide no-follow links but does they help you in anyway? Can get you plain old referral traffic, right?

Some would suggest brand awareness. But I don't agree to them.

You put links in a natural way if they get some exposure then its good for them. Thinking of brand awareness and then putting links will definitely end up spamming the host site.
