There seems to be a strong vibe of jealousy around signature campaigns that pay a decent rate these days.  And OP, I'd never even heard of Bitcasino or its campaign, but if you think there's some shenanigans going on in it, you might want to contact the project owners.

Now, for these two:
Campaign managers have been known to make the maximum rate for the campaign as part of their hiring--I've seen one other case of that, and it was actually a campaign manager who was registered as Legendary member when he was lower than that.  If I recall correctly it did turn out to be legit.

As far as the negative feedback, it's from DT members but it wasn't left because mich scammed anyone.  And a disclaimer: I haven't read the Bitcasino campaign rules, so I don't know what their policy is on members with negative trust.  But all of that aside, I'm not sure why you're so upset about these things.
