I think campaign manager should consider this rule. and allow users to leave the campaign if they want to after finishing the running week..
It's true, it's not fair for those who work for weeks. But these rules will still apply so that all participants can better support the project to completion. In my opinion, there are a number of campaign managers who give participants to their signature campaigns the opportunity to remove their signatures but must be reported in advance. Without reporting, all bets will also be deleted. I think this is fair enough for participants.
why you said it's not fair? as you can see usually that rules already there before you join it
so it will be good if you not join it at first and just choose another bounty
I think he's just saying a general thing. not complaining about a specific campaign. its same with almost every campaign. and he's right. campaign managers should not force this rule from beginning.
