Not a problem. You in fact saved the next person to get scammed by this innovative trick.

The flag is fine. However you may need to update your OP with the flag link which is this: https://bitcointalk.org/index.php?action=trust;flag=2587
And there is a topic somewhere which is about to request supporting or opposing a flag. Post the flag link on the topic to with the request for supporting it. (Sorry, I could not find the link of the topic or I would do that for you)

These tags so far in his profile and the flag will work as a massive warning for others and hopefully no one else will get scammed by this account again.
