I think he'll probably pay for the sig campaign going for a longcon on the casino instead.
He said he will pay "trusted" members upfront for 50 posts so I would say he would pay only this amount to earn additional trust among members. I also see that he did not put a limit as to how many people can participate (which is unusual for a new site as they are generally not large enough to have a large advertising budget). By getting more people to participate they would get more people to deposit funds at their site and they would likely hope they can run away with customer funds within a month when the amount of customer funds gets large enough.
I do see that TECSHARE removed his positive trust so he is no longer a trusted member.
I asked him about member limits, and he says he is considering limiting it to 50 members, which although a large number isn't unusual, I think. Also, according to him, most users would get paid upfront - at least judging by his example. I would still prefer escrow though.
EDIT: hilariousandco beat me to it...
EDIT2: that reminds me: what about the suggestion of editing the OP to contain information about whether or not a campaign has funds in escrow? It currently details those that pay upfront, but I think this would also be useful information to have.
