I've found few complaints for these programs during sorting off received reports.
HYIP's:
Prolexbiz.com
Thedrfund.com
Wortrade.com
Cnnfxclub.com
AutoSurf's:

Tame-the-net.com
Invest-N-Surf.net
Adgateworld.com
ForumTraffic.biz

According to the reports, the admins of these HYIPs used scam tricks or never pay to the program members (at least for those members who sent the complaints).
Be careful! DON'T invest in this scam
