This brings up a big issue with this type of gamification. If someone prescribes a solution which has a superficial short term effect (think painkillers, etc), they may be rewarded in 'points' (e.g. money) because the patient is able to see a direct effect. This would reward treating symptoms rather than the underlying problem and could result in sub-optimal treatment. Unless this website is planning on adjusting rewards based on long term effects on the order of years, I'm not sure how this would be avoided.
Perhaps this is a side note to your point, but if when you say "ect" you mean electroconvulsive therapy, then I'll note that ECT has excellent efficacy for major depressive disorder among others and is well-studied: http://en.wikipedia.org/wiki/Electroconvulsive_therapy#Effic...
It is hard to believe that anyone would want an electroconvulsive therapy based on an Internet advice. Even if, no doctor in his right mind will perform it just because the patient demands it.
EDIT: etc, as in et cetera
