Can we believe those free Referral Builder sites?

Don't believe such sites,They are making us to register in the down line of the paid members only ..Very rarely, they are offering some sign ups to our site and unfortunately, no one is active in our site.It seems they are making the sign ups themselves in our down line.If you are ready to be a paid member, you may get the referrals (innocent free members). Apart from that, I don't find any use from them..I became inactive in two of such sites in the recent days.

I was checking some of those referral builder sites too and I'm not willing to subscribe to a bunch of their fishy offers and then make others to do the same.
I've checked some PTC forums that offer referral exchange and downline builder,but haven't try it yet.

Not all of these sites are legit, but this one is. I use it and ive gotten 3 items from it before.
Check it out and sign up useing this link.
