Unfortunately we don't have any chances to fight with scam. Since there are a lot money here, scammer will be here. And we can't do anything with that.
I totally agree with you as long as they have a chance to scam they will still do it. Like in this community which can give you a lot of opportunity gain profits thru investing/trading and bounty campaign these people will pop out anywhere in this forum. We can't blame the people who are blinded by greed.
