Some bounty managers do have red trust account like you started by I have seen few ones doing diligent work after bounty ends, they distributed as promised, there are various reasons one can get red trust, its not always about scam
Correct, you need to check what the reasons behind the red-trust mark. But it is much better to choose the green-trust accounts or at least neutral trust. I don't underestimate managers who have the red-trust marks, I just lead people to choose the safest way and minimize risks.
