They can create more, as seen here. If you want to truly shut down toxic characters, as you so claim to be after, ban IP addresses. if they cannot connect to servers because their connection was banned, I feel as if it would be a more effective punishment since they cannot harrass summoners under a new alias. I know I am not the only one who feels this way because looking through forums every now and then, I pop up on multiple people who ask this same question. The ball is in your court Riot.
A disappointed summoner.
Unfortunately you don't know how the IP addressing works or how major account locations work. If you ban an IP you could be bringing down a university or college which uses 10 space addressing and natting to provide connectivity to students. You may not like this but bringing down a 100 students to get one toxic player permanently cannot be justified.
Also with the internet you can get 2 or more people playing from the same household, one nice, one toxic. Again won't work. For the kicker, the player could be going to a free location and randomly playing - again won't work.
These are just examples as to why you cannot ban by IP address.
