Well guys I am sure alot of you know about what I am going to post but for those of you that dont, I hope this helps.
First off, make sure if you buy MSP cards they are from your region. But you may have also seen sellers advertising 10,000 points for like 20 bucks. Well what this is is an account that they will send you. You will get an email and password to recover a silver account that is already loaded with the 10 000 points but you will be told you only have 24 hours to spend them. The reason for this is because the points, and or account was stollen from someone else.
And to top it all off, if you do this and buy DLC content you may get caught and loose about 35,000 achievement points, or half of what you have. Take it from someone that knows. I had a friend that it happened to!! wink wink. :(
