It's very sad for me that someone got scammed from forum. To be honest we can't stop this kind of stupid from get scam. I can't believe that whoever hold 7+ btc on his Electeum wallet he don't know about warning that he should not input any code that he have no knowledge about that. Also we don't know really who is scammer. As a DT we tag when someone got scam or if we doubts or suspect any scammy activity. I don't think even forum admin could help this kind of stupid. What will do with IP address if scammer use VPN or Tor browser? Scammer isn't really smart from us? So many warning post but no one bother to read, so how can we help them? If you stop PM then they will contact by mail or telegram.

Actually we can't stop them if they are not careful with their fund.

I can't see victim made any help post. Even he had not botherd to search forum even there is Electrum board. After got scam he have made thread and we can't do anything without tag scammer.
