In Kill Confirmed, you get +50 for confirming or denying a kill; however, if you collect your own tags, you get +250. So the goal is to keep collecting your own tags in order to gain massive amounts of score and EXP.

Pros:
Rank up quickly!
Doesn't hurt the team considering you're denying most of your deaths.

Cons:
Usually you will go negative, so your K/D will drop.
This could be considered boosting, so there is a chance you could be banned or reset.
