User blog comment:Fistful of Force/Report people for being toxic, not playing badly./@comment-5263329-20121225175526

I rarely ever report unless someone directly and intentionally ruins the fun of the game I'm in by  flaming excessively, intentionally feeding (and I mean intentionally as in touching down at the enemy summoner pool for the whole game and not doing anything else), etc.

If someone is unskilled I make an effort to try and make them slightly better players, but I never report unskilled players, unless they're flaming other people for their own badness.

For example, a graves at bot lane blaming his jungle yi for not ganking their lane when he constantly pushes his lane to the enemy tower and blaming his support soraka for being unable to do anything when they get ganked by the enemy jungler as a result.

In which case I don't report them for being unskilled, I report them for verbal abuse.
