Any kind of reputation or trust system introduces a power structure, thus inherently making people unequal. In the forum's case, you'd be talking about Staff, DT and/or users who just have a high trust rating. This is a crucial part of pretty mcuh every society, relax.
And boy, I'd really love to hear from more of the campaign participants themselves. Some have spoken up, but most have not and I can't imagine that it's because they don't have an opinion on the matter.
There's really no need to do this. There's a very good reason why they aren't complaining, i.e. they are not very good posters and need the campaign for its income. If they were certain that they could strike a similar deal elsewhere, and had integrity, they'd be more willing to speak up.
And I think you confused Secondstrade with Bitmixer. Bitmixer was automated campaign, not Secondstrade and they a lot of shitposters in their campaign, until they decided to hire Lauda. Secondstrade campaign wasn't that bad.
Ahh, the good ol' days until the agencies came knocking on the door.
