Ofcourse it is!
Nowadays, I notice most of bounties have strick rules, making bounties more organize and I like that Bounty Manager requesting Proof of Authentication to limit scammer .
It's been one of major mistakes of bounty hunter like me not to read rules and requirements of each bounties ending up not getting stakes so it's very important to read and understand each rules to ensure that we're doing the right thing and not wasting our time and effort.
Yes, i think that the bounty managers need to be strict in joining bounty campaigns, so that the bounty hunters will work hard, and will be disciplined. I strongly agree to this thread, because all bounty hunters now will not waste any time doing their works.
