I think some of you may be confused about what is happening here. We didn't change a promotion in the middle or anything. We just reduced the amount of free money users could earn from achievements.
So after all, this is what you are accused of and the OP and others here in BTT. If it is true that the reduction without personal warning is 90%, then this is at least incorrect in relation to the user. I, too, would be wary of partners who might do this.
This is the meaning of the accusations, as I understand it. And of course this is not any free money, but these are legally earned bonuses.
