Is this exploitation?

Basically, I just played 2 games in a row of dominion and there were no other human players in the game. I can rack up a really high KDA and get basically free IP and Exp. Is this allowed? http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1762235913/208372096?tab=overview http://matchhistory.na.leagueoflegends.com/en/#match-details/NA1/1762245530/208372096?tab=overview
