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
I think its obvious that you are always going to receive junk emails and promotions maybe even scams to email addresses that are available in a public spreadsheet. Its always safe to use a separate email for these purposes.
Also it would be better if bounty managers mask the email details .
