It's an easy decision. You want to protect the few who joined the campaign inspite of being aware there is no escrow and that they are advertsing scam. You're ignoring all those outside the few threads who can't see the warnings exposed to the ads and thinking this is legit.
There is no reason for any trusted escrow to help them. In the current situation they're getting no one and campaign is dead. If any trusted escrow helps them they are responisble for anyone getting scammed by them due to their ad.
No, it's not. This campaign pays something like 75% better than the best available non-risky signature campaign. It
will fill up and the same advertising potential
will be achieved
regardless of whether or not someone escrows. I want someone to escrow so that less people are at risk of being scammed. I'm aware that's not the case right now but I'm fairly sure it will. Once it does someone needs to step up - perhaps not yet though.
You want to protect all those who are joining the campaign even though there are warning signs? They're joining knowing it is a scam and that their ad may cause someone to lose. They don't care and want their pay. If they get scammed let them be.
You don't care for all those who can be scammed by the ad? Instead of making escrow you should be trying to find ways to prevent it.
