How are players like this not IP banned?

death threats and inside the game was flapping their gums at me and another player that I wasn't queued with. just incase my ingame report doesnt get them banned, here you go riot. gg.

We're testing a new feature that gives the option to view discussion comments in chronological order. Some testers have pointed out situations in which they feel a linear view could be helpful, so we'd like see how you guys make use of it.
