These ones frequently expire. There is a possibility that the ones they were running either expired or are old.
Also there has been a crackdown by an unnamed advertiser for certain reward site platforms (ie shiftcode sites and similar sites) and they are pulling offers. I know TT wouldn't be affected by that but I"m not sure about moneybistro since I'm not a member. They might be affected.

I read about the crackdown on SR Forums. I just joined Moneybistro, so it really doesn't matter me one way or the other about them, I just happened to notice that none of their links worked.
I am happy with SR, QR, and TT as those are the main sites I use anyway.
definetly check out the TT boards for those offers because they tend to post threads on when they will expire so that should give you a heads up for other sites that don't have forums or tell their members.
