I think I did that. He is currently online and no reply from him so its a scam for sure.
You left him a feedback. but did not create a flag.
Go to his feedback page
https://bitcointalk.org/index.php?action=trust;u=2509723 , scroll down where you can leave a feedback to him and there is also an option to "add a flag" .
Shouldnt type 3 flag be more appropriate here since he got scammed by Loki888 and lose funds?
