IP bans are effective only if the user is using a home internet connection. If they are using a corporate, cellular service provider, torrenting, or VPN internet connection, then an IP block could do more harm than good. In these situations, they have access to so many IPs that to block them all would take a long while and also block many (potentially upwards of 100s of thousands) non-vandals.
