I came across this site, AGLOCO, from a famous SG blogger's site. It seems reliable and ok. The most important thing is, IT'S FREE!! Give it a try!.
What is Agloco? Why everyone is talking about it?
Agloco mean A GLObal COmmunity. Once a user signs up for free, they are asked to download the Viewbar™ software (which is currently still in closed testing and will be released in mid April). By running this multi-functions Viewbar™ (e.g search, anti-fraud, contextual ads etc), Agloco will pay each member money & share depending on the Viewbar™ usage (Max 5 hours per month). Advertisers will pay Agloco to display contextual ads, while Agloco will reward their members for using the Viewbar™. This concept is similar to YouTube rewarding users who upload quality video. Agloco also run a referral system which will further reward member who bring in new members.
