Really toxic player

This guy, was just wow, to say the least, he got really mad at a player who was low level, as am I still learning the game, but i was having fun even though we were losing it wasn't even ranked, he went on about how he hopes my parents die, and this other guys parents get shot in the head.. and how he's going to use all his alt accounts to report me and my friend who just blocked him, I just said to him he is a new players, it's a game you're not going to lose your arm over it, so I said relax, he said but people make millions on it this game, I said and with your attitude you're not, and plus i'm live streaming right now, he just got more and more toxic as the game went on. I just wanted to leave the lobby and forgot to leave a message of the toxic statements he said but I did report him, is there anyway I could still do that? 5:20 to 5:30 eastern time today on the 23rd. I have him blocked so if a support team is reading this people I tried to do the support live chat, but wouldn't work for me, if you go to my block list, he's the only one i blacklisted, his name was a bunch of random letters, i'm still new don't even know where to find the block list lol.
