I saw him at this place: https://bitcointalksearch.org/topic/wts-stealth-bitcointalk-full-member-accounts-001125-btc-each-1654387
his profile is: samward ; profile link: https://bitcointalksearch.org/user/samward-299272
after searching a lot I have found that he have a number of alt accounts selling cheap accounts and I also have found some hero and legendary accounts of him. I will post that list of his accounts after confirmation and if he did not replied me.
I hope the admin or moderator of this forum will help me
Sorry this happened to you... Scams are not moderated on this forum i'm afraid. What CAN actually happen is: you can create a valid scam accusation, DT members review this scam accusation, if the DT members agree they place negative trust on the scammer's account, warning everybody not to do business with him/her.
If you're really lucky, the scammer values his account more than the BTC he stole, and refunds you... Altough i guess chances are slim in your case (since his account is worth less than the 0.018 you claim he stole).
you should probably read this topic on how to make a proper scam accusation:
https://bitcointalksearch.org/topic/scam-report-format-use-it-to-make-scam-reports-properly-260073
you'll need to include tx id's and screenshots of your PM's to make a good case.
On a personal note: account selling is frowned upon in the community... Wouldn't it be better to make a new account and just use it honestly untill you get a good status by yourself?
Follow his advice. Don't accuse random members of being samward. It is true that I have bought accounts from him, but you accusing me of being Samward and also threatening me to give you your money back or else you will contact the moderators has no support. I have told you many times that I am NOT samward. Next time, please provide your proof before you falsely accuse someone.
