I did many twitter campaigns and for many bounty managers I have the same problems:
1) I have to spend a lot of time to know when the campaign will finish -> why you just don't make a RED text in first message on TOP saying " BOUNTY FINISH AT...." ?
2) I have to spend a lot of time when the campaing has finished to know if I have to do something (Like making KYC or filling a final form etc...) -> why can't you ask this information when we joined the bounty?
So please take my advices..... as bounty managers ask us to follow the rules, please try to make our job more faster and easier as you can...
because in my opinion bounty manager can not ensure the right time to tell when the bounty is finished, because most bounty will be finished if the ICO of bounty is finished and most ICO that increase their sales time, so bounty manager can not tell the right time to when bounty finished and about KYC, maybe at first dev does not suggest bounty for KYC and by the time ICO is finished and bounty will be paid soon then dev make new rule for bounty to do KYC, I think bounty manager only runs the task from dev, then in each we follow bounty there must be a rule stating that the manager can change the rules at any time, and if you join the bounty means you have agreed with the rule.
