We're in the start of a series XP grind, it happens every season. There are lots of angry people forcing themselves to do PvP for the FoMo rewards. It takes time for them to investigate PvP incidents, though they should block people from putting "Target to ignore" on your own team members. And personally I thought you could report people for spamming with quick chat, especially if they're not using to help direct the team at all.
