FWIW, some signature campaign on this forum use escrow. So i would escrow service works, but i would never claim it works 100% of the time. Although some of the escrow on the signature campaign also act as campaign manager.
however, i am having a hard time understanding what this thread and poll is for, are you looking for members who offer escrow services?
I believe this poll created with purpose to know average member's experience using escrow, not looking for escrow service.
