Alright seriously this is the third time someone has come to me and reported being scammed by someone saying they're me.
What I don't understand is why don't these people don't check with me on LG before doing the trade?
If someone comes to me and says "Hey this is mod x's im/skype add him and he'll mm."
The first thing I'd do is contact mod x and ask if it was their im/skype or check the information posted for contacting them against what the person I was trading with was saying.
I'm just added a sticky to the trade section about this.
Use you can make a report but it's not likely we can get anything back for you. Though those involved will be banned.
