If by that you mean say Buns has 3 accounts and he is the best in ladders so its 3 times more difficult for opponents to get top rank because they have to face him 3 times, I would answer that Buns deserves his rank by being able to beat you 3 times.
Buns can also beat you 3 times, and then have 2 of those accounts surrender their next 50 games. You now have 2 losses to players rated <1000, possibly even falling losing your shot at the top 50 as a consequence.
