It is always good to use a trusted escrow if the campaign is posting by a newbie user but if they do not escrow then no one can force them either. The participants will join the signature campaign with their own risk.
An escrow is def good, thats why we have chosen game-protect, the name says its all "game" and "protect", everyone wins.
Just so we know you are on the same page as everyone else here, you're talking about this user:
game-protect?
It seems you missed a few reasons why most people here find it hard to trust that guy.
See this for referenceI would suggest hiring a trusted escrow for this signature campaign or else you'll have a hard time earning trust within this forum.
You can pick anyone on this list
