If I remember correctly, they were deposited funds for this campaign in escrow with the manager, and he made the payment from there.
Damn things happened so quick... We might just be having another not your keys, not your coins campaign v2 
Btw, by manager do you mean eXch support or different Bitcointalk user ??
And is this escrow in public domain for verification?

Even if there is no direct reward, it is a scam scheme, and we need to fight against such people. It's not just a matter of eXch service, it's a matter of general hygiene.
Fair enough
