I will repeat this one more time: if the person was a victim of these scammers and has evidence then they should open a scam accusation, create a flag and leave negative feedback on the scammers account. I know few are DT members but you don't need to wait for DT member to leave negative feedback on the scammers account, if the scammers have a lot of negative feedbacks there will come a time when we just report this site to the admin that I think he will take action
That's true if you have valid accusations just create a post don't think it's useless because there are already many accusations even if it takes hundreds of accusations it will still matter, it will create a snowball, and time will come that they will be ban here or authorities will take action and pull them down if you have been scammed do what is right and do your responsibility, for future references and to warn newbies or those who do not know yet.
