From your table, the monthly salary last from $180 to $500 (from the 29th to 1st positions).
I don't think that people can earn too much money in the forum like this as their full time job.
In average, for my rank (Full Member), the rate of btc campaigns ranged from 0.0012
BTC 0.012
BTC or just higher a little bit. $50 or $75 in some campaigns with bonuses for top merited participants.
Maybe, as their full time jobs, they do same jobs the same time, from signature campaign, to graphic designs, signature designs, Escrow service, as well as campaign managements, but I think that they have to work so intensively to hit such total monthly income.
It's a really hard work.
