Tracking IPs doesn't help that much. Even non-technical trolls discover proxies quickly. Because you cannot stop them so at this point it is less about saving resources and more about harm reduction. It's unfortunate some people who probably would change get caught up in it but it's really a small price to pay(their not having their comments public but still being able to use the site normally) for the greater enjoyment.
