The moment I saw that he advertised on the marketplace, at first glance I knew it was a ponzi scheme.
OP, I highly suggest that you create a flag against this user so newbies may be notified and alerted. There is a significantly high chance that he will be scamming in the forum and it is our job to avoid that. I will keep myself updated on this thread until you create a flag. Nonetheless, as
@TalkStar did, I will also tag the user on my end.
I also observed that you opened a scam accusation against the same OP but you failed to post it on proper format. Nevertheless, I am happy that you also took the initiative of reporting the user. Thank you!
