Okay, so payment has not been made. At least can I at least remove safely my signature ?
You can remove your signature campaign because the stake of member in signture campaign are calculated and manager Jamal has said member this campaign can remove signature in last week 
.Agreed. Jamal has already confirmed participants can remove signature if they want to.Now it is just a matter of finishing calculation and asking the team to pay bounty campaign participants. These processes can run independently.
