Nice to see a campaign that is probably a scam and advertising one at least?
This is not a scam , or atleast I don't see any reason for it to be one.
I first thought the prices were 0.0003 and 0.0004 BTC , but upon closer inspection , it is one order of magnitude less.
To put it into perspective , 40 posts by a Newbie (or 30 by a Jr. Member) on this campaign earns the same amount as one post by a Hero member on the PrimeDice campaign.
A Jr. Member will get 10x the payment per post once they switch to PD when they reach member status
Here is a small list for comparison
This Campaign - Newbie - 1.8c per post
This Campaign - Jr.Member - 2.4c per post
Primedice - Member - 24c per post
Primedice - Full Member - 36c per post
Primedice - Sr. Member - 60c per post
Primedice - Hero Member - 72c per post
So , even if a brand new person joins this campaign for all their 60 posts min required to get to Member , they will get only 0.0021 BTC ( around 1.26$ )
Note : Primedice yet does not have the highest payment , but I've used them as a guideline as they are the most stable service.
