repeatedly the bounty hunters ask about scam project or not. but the definitive answer is we don't know it. because once again I explain to you , who knows the project is fake or not just the owner of the project itself. even a bounty manager doesn't know the project he's handling. so what we can do is choose a project based on how we feel.
And the funny thing about all these bounties is there are a lot of guys who recommends to other people reliable bounties. But as you already mentioned - there are no confirmed info in public about any bounties nowadays
