I do not think this has to go in Tutorial since it's not for CF but more for MPGH Traders.
So lately I've seen few thread about "100% Legit Flagging services"
And I came to conclusion that's a lot of Scamming OVERTIME.
Here's a Method to PROTECT yourself from These scammers IF You are a legit player and there's no Middle Men in the trade/Situation.
You will make a Ticket before giving the Flagger the right to make one.
Then if he dosen't try to take any Harm action you can remove the thread.
If it turns out he is a Scammer. the One you made will either ban the account or succesfully Flag your account before the Flagger.
