that list should be upgraded, in the way that it list the it list the most profitable campaign in the first spost then the second ecc..., and not how it is right now, it would be easy for everyone to join the best one
and divided for newbie and other members, for example dadice and bit-x should stay in the first 1-2 spots for full members+ and for fullmembers- 777coin should be the first then the others
There is no way to do that as what is 'best' or most profitable depends on the individual's posting habits and rank. Rates are constantly changing and sometimes people even get better deals than stated in the op if they're a quality poster etc.
