So people are saying that they are getting scammed. A tip to find out if someone is legit or not is to do this.
1.View their profile
2.Scroll Down to Recent Activity
3.Click forums
4. And see what they have posted

If they have posted any kind of forum such as "Looking for a ghost lobby" or "Can someone get me 10th?". Theyre not legit, they are scammers.

If they have posted forums in the past saying that they are hosting lobbies such as mw2, mw3, cod4 etc.. then you will have less chances of getting scammed by them. And ask if you can pay after. Most scammers will say no, but some legit people will say yes, or ask if you can pay half before and half after.
