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 ??
I thought its the exch support itself distributes the payments because they are in charge of the reward process.
Tons of convo already happened, and OP also has not been updated yet. Would like to ask what's remaining domains on the list so I can get up more reports.
