FusionCash is not like a restaurant; our paying customers aren't you members but rather the advertisers and survey providers. Members like yourself are independent contractors, and you get paid rather than paying us (like you do with most businesses).
We work hard to balance the needs of our members (without whom there wouldn't be a site) and our advertisers (without whom we couldn't keep the lights on). This means a number of compromises: we have to limit the amount of bonuses we issue (we don't earn anything from it being your birthday... not to mention that with 2.3 million members we'd be issuing approximately 6000 birthday bonuses per day on average... not to FURTHER mention that if there was a birthday bonus, people might tell their referrals to choose a fake birthdate which is coming up soon so that they can get an additional bonus [and an incentive to falsify information is bad]).
As for survey qualification, it's a complex issue:
1) Surveys are often routed through two or more survey systems, and they rarely share information: so you may have to "qualify" for a survey multiple times.
2) Surveys are typically targeted at one demographic "slice", for example "males in the midwest". Once the quota of "males in the midwest" is full, you wont qualify anymore. You may see other people being credited for the same survey, because they're in a different 'slice'.
3) Since your qualification depends on your demographics (which you can't control) different members have different experiences with surveys. For some, who are among rarer demographics, they almost always click through, qualify and get credited. For others, among more common demographics, they have more difficulties qualifying.
To belabor the restaurant metaphor, a survey provider might "order" 200 survey completions from "males in the midwest". If we delivered them "females in new york" instead, they'd rightfully be dissatisfied; like getting fish 'n chips when you ordered a steak. This is why taking surveys can be frustrating, inconsistent work. If there was a way to improve it, we would, but you can't really tell a multi-billion dollar multinational research firm that their survey platform "needs to be fixed"...
