Bounty managers please kindly start hiding emails in your spreadsheet because I always like using new email for bounty participation and I surprised that there are many offer mails in my email account, some are free airdrop some are affiliate marketing offers, I still remember that some people are selling email addresses online, it will be easier for such people to go through bounty spreadsheet and pack the whole email address
You cant do anything if the manager do have their own ways neither they would hide or show all of informations in the spreadsheet but i do agree on the point that there should be some sort of privacy but it can be helped because they would stick out to their rules. Therefore, we should use our common sense and make use of new email everytime we do participate in bounties and dont make use of your main email because that would really be prone to be taken and received lots of junk emails.
