that is just garbage. How can they even think it is fair to reduce the bounty campaign? The campaign did a lot for them to receive the funds collected. I know sometimes the bounty amount is high in relation to collected funds. But than you will have to make it %-wise. That is a scam and really destroys all reputation of the team and the project.
Unfortunately, the RepuX team ignores all complaints. And the reward for the campaign members will not change. we have to accept that.
