Ddos threats should result in suspension/ban

Recently, I've been accused of hacking in several games. of course I have no programs or anything other than overwolf replay running on my computer while playing. But yet, when i finished my most recent game, i was accused of both hacking and smurfing by someone who claimed to have traced my ip. Neither of these are true, and while I explained that to him, he remained adamant about it, and began to threaten to ddos. this isnt the first time I've recieved these threats, and with mainly my personal safety in mind, i feel like Riot should take steps to stop players from making these threats simply because I have known of people who have gotten hit off their internet by people from the game. I know most of these threats are empty and most likely won't actually happen, but I just want to be safe in case the occasion occurs where it was not a hollow threat and my internet is attacked, especially due to the fact that I am in college dorms and to do that would mess with the entire buildings internet.
