He has been doing this since 2022, idk if that got unnoticed or if that is okay on this forum but one thing is for sure, this user is a scammer and liar.
You cannot be sure that he is a scammer if there are still no proven charges against him. He probably went unnoticed because his service is not interesting to anyone here.
What you can do is present all his fake and alt profiles here, maybe create a flag for his main account and ask for support from DT members.
. Maybe ban is exaggerated but it will be optimal if DT members leave a negative or neutral feedback. I don't leave a feedback because it won't be visible, it will only be in untrusted feedback
