With respect to what I bolded in the OP's post, they are not helping anyone, rather they are harming everyone, even themselves because karma will one day catch up with them.
First, those who are hired are being harmed, because they might one day be caught, if the case is taken seriously and will face the wrath of the law. In a way, their reputation is being tarnished for just a peanut, because I am trying to imagine how much they will be paid for such service. They do not know where they will be in future and by so doing, such action might be used against them.
Also, investors who fall, victim, are being harmed, by deceiving them.

So pls, if you are I doubt of the team of a project, after carrying out adequate research, do not invest in it and do not mislead others.
