Chat restriction for Asking them to report an intentional feeder?!

I got a chat restriction from the last game. Bot was 0/9 and still dying often so I said stop feeding bot at which point I was called a %%%. The twitch bot later said he was going to intentionally feed to annoy me. Why did I get a chat restriction for this? Is it because I said twitch called me a %%% in chat and thus got logged saying %%%? What did I do wrong here? I asked them to report twitch in all chat and got yelled at for being mean. I did lose my cool with all these trolls and kept asking for twitch to be reported for intentional feeding, which he was doing, going as far a entering their base with all turrets up to do it. Help me to understand this please! I really like this game but if I'm not going to be playing it again until I find out what I did wrong here, since I don't want to be punished again, but I still want to be able to communicate with my team.
