The first sign of red flag for a fail signature campaign: the bounty manager is inactive. If you sight them, better left it and stop wasting your time on it anymore. Too much risk for doing all the work and receiving nothing in the end.
unfortunately I already went through the sad situation of being active for 2 months in a bounty campaign and then I had to wait 4 months for payment, there were nightmare and irritating days and at the end of 4 months when it was just time to receive payment I see that there was a 500% reduction in the initial value, something shocking. Again I went to participate in another bounty campaign and this time I had the same bad luck but it was worse because I waited months and never received anything. this bounty campaign payment scheme is very wrong, i think people should demand that payments be in bitcoin or litecoin or some altcoin already established and with low transfer fee
