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
Professional bounty managers have long been using the practice of hidden data in spreads. I also don't like it when my email is visible in the public domain in some kind of spread.
In addition, many use the same email to which their account is linked, which gives attackers the opportunity to use this data for a targeted attack.
