OK, so I am sure if you are like me, a keen Xbox and CoD player that has got bored of playing days of the game and just want to get to the highest prestige as soon as possible, you have searched the Tech Game being the most reliable way to do this. In some ways you are right but in others you are severely wrong. Put yourself in the feet of someone who holds a J-Tag. Now, the only way your going to get into one of these "FREE" lobbies is if you find someone who:
1. Has a J-Tag
2. Is willing to do it for free
3. Is willing to take there spare time to help strangers over Xbox
4. Is willing to go through all the effort of helping people and getting it out that they are doing "FREE 10TH PRESTIGES"

The matter of fact for all you Rookie Tech Game users and all those people that want 10th but don't want to play is that it is very unlikely that you're going to get it done free, but it is not impossible. I have been lucky enough to find someone that has got me to 10th on CoD:WaW and someone else who has got me 2 prestiges on CoD:MW2. I seriously think that if you are looking on Black Ops for this you are seriously wasting your time as quite frankly no one who has a J-Tag is going to miss out on wasting 15/$20 on getting a stranger to 15th Prestige for free when they can make this money. If you are looking for free 10th on the other CoD's I think that you can be in luck if you find the right person. But otherwise don't ever trust or look at these "FREE 10TH PRESTIGE" posts as they are not going to help. You are just going to have to be in luck at the right time!
