I am not sure that bounty manager should be blamed because bounty participants are not paid 11 months after they were promised to get they rewards. There is only a possibility that team BQT&IOU give zapo this task (to pay users), and he is take tokens and disappeared, although it is unlikely option. Signature campaign is paid in full and on time, though it was abruptly interrupted before end.
I can only say that professionals do not behave this way, and if this thread is not started they would never provided any explanation. Maybe you can make a suggestion to their CEO to come to this forum and explain some things?
Does anyone have at least an approximate amount of money they need to pay to bounty participants?
