Does it mean that managers who are known to be trusted people can manipulate spreadsheets as well?
not all managers have a good reputation in the forum, you can certainly see some managers with newbie accounts on the Bounty board. Have they built their reputation in campaign management? not that I don't believe it, but if I were a bounty participant of course I would be skeptical about how they manage the campaign. although I am more sure that they are just Newbie accounts, not really new forum users.
Hamilton closed the spreadsheet for stake calculation. after that found an address that got the calculation but never registered for a bounty campaign, how does the manager explain that?
it not problem account "Newbie" to manage campaign. In Bounty Hamilton case, he not showing spreadsheet after campaign ended and he put some account and other wallet to farm rewards campaign.
On the other hand, for us "Newbie" rank, we are really grateful that there is a manager who launches bounties on "bounties" board.
Because some managers like "Legendary" or "Hero" rank only launch signature campaigns, so we can't participate.
