I know his campaign is full and I cannot join. Even if I could, I will be thinking twice about this campaign.
It is reasonable to delay payout if OP is busy and cannot find the time check posts, but OP has already calculated all the payout since yesterday. Why did OP not send it right after and post about payments in 24hours? I question his intent. I believe OP is deliberately not sending out payments to retain those members, who would like to leave the campaign, for a few more days of free ads.
This seems like a valid argument.I think OP should make a new rule that members can leave the campaign right after the end of week or after a few hours the week end.Even they get payment after 2-4 days but they don't have to keep signature for this time.
