Do they get banned if i report them by asking passwords?

Yes they do

he is correct because when s scammer makes a deal for your acount and says they pay you cash they just get the account and never send the money

so can a smod ban this guy?:

Of course. Dont even go near people like them.

PM that to an SMod or admin (Red or blue names). Don't make threads in Support.

Yes, I think they will, but I wouldn't bother them unless you show/send them the screenshot or some other form of proof, you will just be wasting their time.
