There is nothing anyone can do about it, maybe that's why bounty hunters are even getting cheated from time to time, this crypto space is a free zone for all kind of activities, scam, hacks and cheats knows no boundaries on here, just accept your defect this time and move on, this isn't the end of the road, some projects still cares about bounty hunters and they will keep their promises
it is often happen to us and not be the first time since many bounty campaign launched. scammers know how to cheat us and they could ask us to do something meanwhile its useless. but we should not give up with this condition , as you said there are alot campaign that still fullfiled their promises to bounty hunter
That is part of bounty hunting, I've been into several projects where I spent weeks or sometimes months promoting projects and end up being scammed or unpaid. It's part of the risk. This risk can be reduced if you will review the project, the terms of bounty, and conditions before joining. If you think it is sketchy, and not comfortable with the terms and conditions, don't join.
unfortunately bounty hunter didnt read the rules carefully , and complaining about their work meanwhile its broke the rules. sometimes mistake come from our side.
