Do you report for other people's connection problems or not?

Dear Riot: I understand that you don't actually like me moving too high in rank, but why inflict on me the duo that alternated between feeding and disconnecting all game and blaming suddenly terrible lag? In the interest of fairness, I must insist that they be put on the opposing team in my next game.

Seriously, though, is there any point to reporting people for intermittent connection issues? And if not, what should be done about them so they don't poison my game? Or at least someone else's game.
