Bounty hunters should be more responsible, as long as we take any project in work, scam projects will continue to born, we should be more strict to new projects.
And that's the right behavior!
Bounty hunters (not everyone, but most) do not check at all who is behind the project, they are only mindlessly applying and promoting bounty programs. Many times, even if the ICO is officially announced a scam, they still do not stop promoting it. When this is changed, scams will also disappear.
