You shouldn't receive red trust for something like this as long as you stop everything related to the project as soon as you're notified/you found out.
Was there no ANN thread/official team account?
Do bounty managers have no responsibilities? I have seen multiple people receive negative trust for
participating in a scam bounty campaign, wouldn't the bounty manager be subject to the same treatment? Or is he allowed to "back out" when he learns they are a scam?
I have the same opinion. The flame focus should be on the malicious project, once discovered.
Woshib stopped all activities with them when as soon as this has been brought to his knowledge.
Also, he is managing a couple of other, legit, bounties and he's good at it.
I think this negative feedback should be turned to neutral.
You can't humanly monitor every page / paragraph, and check every day if there have been a change or not ...
What Woshib did here by withdrawing from the agreement is the expected behavior after the issue has been brought to his attention.
There is no malefactor association here, and Woshib helps to spread wealth to some people taking time to translate things and do stuff.
In the end, all balanced out, is the negative feedback really the way to go here ?

Once again, if he can receive money, he can do a background check on them. It's not his first time, that's for sure. There was no need to "monitor every page or paragraph" an initial check was sufficient and he failed to do it. Also, he advertises himself as "trustworthy" so it's about time he starts acting like he is. If we want to fight the root of the problem(scam projects) then we should start with bounty managers, since that's the first door to knock on for any scam project. Accomplice to scam in any real-life situation is a serious offense, that's why people carefully watch what they sign and who they work with. Negative trust is a good wake up call for Woshib,
the consequences could have been much larger if members didn't out the scams early on.
