So the team member who was trying to threatening everyone us that they will have to face consequences for calling him scammer have already tasted his own medicine by getting banned.Giving him signature ban was good but complete ban to such scammers who impersonate themselves as admin members is best.They try these cheap tricks Just to fool any newbie whom they might contact through PM or they message them so playing these cards but how they don't think they can get caught I don't know.But appreciate your efforts @Ratimov for exposing these scammers here.
This is serious case for proper action, but I believe the forum does not moderate the scam even if had dropped the hammer.
I agree with the ban, it's much better than having to give him a second chance. That user is trying to identify himself as an admin for his personal gain regardless if he is cheating or some other reason. It's never ethical, and yes a permanent ban is a consequence.
@Ratimov, your report has been handled. So this case seems to be closed, it must that is be a good catch.
