I'm surprised that so many people don't even check trust section of bounty manager and later they write how got scammed again.
Bounty manager used to have a -1 in his trust, that is no longer visible, but that did not hold hunters from joining bounty campaign. Indeed this project and bounty looks like scam. The manager cant handle bounty properly, as spreadsheet isnt filled for a month, while campaign is planned to run for 13 weeks. In managers telegram channel (where manager is surprisingly active), it is said that the rewards for first and second bounty campaigns will be distributed in 2 months after second campaign ends. Reminder - second campaign is 13 week long and first ended in 2019 and spreadsheets were also empty.
