$1m / 5200 = $192 average order. With a conservative estimate of 3x markup on product (seems way high, especially if these guys were just middle men), $20 shipping (national, Fedex) and 0 hosting costs they're making 192-(64+20) = $108 per order. $108 * 5200 = 561,600 / 2 / 8 = $35,000 per person per year, or $16 an hour if it was a full-time job. Considering that anyone with the skills to set up an anonymized marketplace site should be able to find work that pays far more than $16/hr this seems like more an ideological exercise or hobby than a money-making cartel. Whether or not you consider it to be worth spending probably $3m+ on investigating, trying and imprisoning these 8 people is another ideological question...
