Why didn't you start it yourself? You haven't tagged the scammer or created the flag. If you are so clear about it, you should have at least tagged him. Asking others to do it without doing it yourself doesn't sound very coherent to me.
Actually I was thinking as hosseinimr93 mentioned that my feedback will not appeared on the profile which will not bring good results and my aim is to warn member which is only possible if DT member tag it.
Regardless of your DT status, here I encourage you to start tagging accounts when you are sure they are scams. Over time, if it turns out that your assessments are good, you will quickly reach at least the DT2 list. So, based on your trust/distrust list and the feedback you leave, others can better evaluate you.
In such scam accusations, always notice that you tagged that user and that (if) you possibly created the tag.
note: I am going to tag the account mentioned from OP to be visible.
