Flex-queues and multiplied hatred

Riot, are we doing anything about groups who multi-queue and spam bitterness and hatred at singular players throughout the game? Seeing a large number of games where this is happening. And the two or three who are flex queued together are sure to never receive enough reports to have them audited for it. Much more, even if it isn't just one of them throwing hatred at you, you have each one say something in their turn, which in the chat log is going to look like they're each not that hateful, individually. Anyway, it would be nice to hear some insight about whether this is being looked into and what can be done about it. I remember seeing this even in World of Warcraft, back when I played.

Much thanks, cheers
