I was either looking in the wrong place or it's not publicly available.
Only people in the campaign can see the spreadsheet. Through the campaign group on Telegram.
Carollzinha once shared a list of Stake,com participants on a spreadsheet in 2020 and I think that sheet is still active today.
And indeed the spreadsheet I see is not in the OP list.
And for those that (I honestly have no idea why) want to know about the campaign members,
here is the list.. but, as I said, no new members are shown in that list until they get their first payment.
