Running a signature campaign without escrow does not mean automatic fraud. as long as he does not owe any payments to campaign participants.

So as a warning for participant
I have tag OP. my warning tag was below, (Removed tag for now)
"Newbie account running (BTC) signature campaign without escrow fund. Be careful before join this campaign. We have past experience many newbie manager skip without pay to participant. My feedback will remove after release first week payment or if use any trusted escrow."
You will remove feedback after the first week. What after the second week and no payments? Then you need to change third time your feedback. How competent is your feedback if you change it every few hours or days.
I just think you rushed with this tag.
