They do not announce selected participants in the Campaign Thread, perhaps the manager chooses another route in selecting participants, such as sending personal messages to selected participants.
They are the biggest platform, if they don't have a budget for new participants, there is no way they will allocate additional bonuses for 4 participants per week at $35 for each participant.
I don't think the OP's problem needs to be expanded further. the account OP woke up from the grave just to complain. I suspect it's part of the applicant who never knows the certainty of the application submitted to the Stake campaign manager.
OP may need to know the number of active signature stake campaign participants. I think it's over 70 participants this time. and if it is made on average each participant gets a payment of $70 every week. OP can judge whether his words are appropriate to say or not.
This is just an assumption, I'm sure stake campaign participants get more. as an illustration for OP not to make jokes easily.
