one report is not going to get the player banned, true. But that still does not mean it is not a legit report and your report weight is diminished for it. Riot almost never rigorously enforces anything, let be honest here.
It will take many reports for the player to even get warned, but you only build a case one report at a time. Plus the ai tribunal only can learn through reports. If enough people report a certain behavior the system supposed to learn that it is not acceptable.
I am all for the system learning that troll pick are not cool.
Actually the name calling and swearing had been enforced quite "harshly" so a lot of bans had happened. But troll wise bans are going to be scarce because is really hard to differentiate what is really a troll and what is simply different playstyle going wrong.
