These are two completely different services and two different campaigns.
I am a little surprised by the decision to increase the pay rate in this campaign, but looking at the big picture, maybe it's understandable.
It is about Tumbler Mixer, which has already invested a lot of money in the review campaign, design contest, etc... They have already deposited the funds in escrow for the signature campaign, and now that they are slowly getting to the point where they expect the return of the investment, they have been announced to be excluded from the forum. So they decided, there is no return of money from escrow, but do as much as you can until the end of the period.
