Freeloading N00B guy

So today I was playing Wrath of Mantis and I saw a guy with viper armor freeloading. Actualy I have seen many players freeloading but the big thing about this one was that he didn't even attacked the boss and just ran in circles in the arena and for just that he got $40,000. I was so angry but I was there for the money so I didn't rage quited but man I was mad.
