While playing some MW2, I recieve a message from a person who says he can give me tenth prestige. I knew he was scamming as soon as I saw "for 1600 MSP" (I also had further doubt because he was a third prestige and I am a tenth)

These were the messages i sent and received:

(Scammer):
Message to all friends and recent players, I can get you tenth for 1600 MSP. All fake codes will get you de-ranked

(Me)
wow, you fail scammer

(Scammer)
no YOU fail because you aren't tenth
(he then inv me to his game)

(I join)

(Me)
See, I'm tenth

(Scammer)

(Stutter), well um this is my other account

(Me)
Oh sure...

(Scammer)
Don't play around, i can derank you with a push of a button!

(Me)
Do it then

He then ends the game and leaves the lobby

(Scammer sends message)

I felt bad, i didnt want to derank you and for you to lose you tenth

(Me)
I dont care, i get into lobbies everyday

(5 mins later)
K fine, i was scamming, can you get me into a lobby?
