Club names need to be monitored
In the past week I've played with players with various offensive club names, ones that include but are not limited to racial slurs, homophobic slurs, and other culturally insensitive material.
Unfortunately, there is no "Inappropriate club name" report button, and as far as I've been led to understand, the monitoring algorithm for reporting does not consider club names at all. Doesn't even look at them.
Riot, you should not be providing a system for people to have a workaround to offensive summoner names. Club names should be monitored and/or reportable.
