Boosting and glitching has gotten to the point in COD: MW2 that having a emblem or title is becoming less and less credible.  Boosting was possible in COD4: MW, but Infinity Ward with their finite wisdom decided to make it all the easier with tactical reinsertion on MW2.

Do you know how often I use resinertions?  Never.  Do you know how often I see an opposing reinsertion and destroy it?  Everytime I come across one, which isn't very often.  Even less common, I kill a guy and then see him respawn on his reinsertion and shoot him again.  Easy double-kill.  I never hear anyone talking up or being thankful for using tactical reinsertion.  Why can't Infinity Ward swallow their pride over putting a tool almost exclusively useful for boosters in the game and just remove it?  Seriously, I see at least one pair of boosters daily using tactical reinsertions to cheat.

It's gotten so bad, unless I know the player personally, I doubt whatever merits they have to show for their skill in the game.  As far as I'm conerned it's all owned up to boosting or glitching.

As far as glitches go, IW just released a patch mainly fixing infinite tactical reinsertions and run glitches.  Here is their post explaining the patch in more detail.  Rejoice!
