You can implement something like... if someone have more than 10 mute from users, get 8 hours chat muted, with more than 20, 12 hours muted, and with more than 30 permanent muted... and maybe ban for people who abuse this, or some rules like only mutes from accounts with lvl 10 or more count.
And you don't need more mods

Like so many of the suggestions in this thread, you're forgetting that it's free to create a new account. People can easily switch IP addresses, so there's no way of banning people.
We're stuck between making it as easy as possible for new players to get started on the site (easy to make an account, free dust from the faucet) and making it hard for spammers/bots to abuse the system. I don't see a way of satisfying both of these requirements without human intervention (ie. intelligent mods).
People seems to forget that we already basically don't need mods on PD.
We have /ignore command.
So anytime u see somebody spamming just use /ignore username and u are done with him. Let everybody else know they can do that and that's it.

The only caveat I've noticed with this is on people who are only occasionally irritating. You mute them, then it gets confusing when other people who didn't mute them looks like they're talking to nobody. Sure the insta-spammers are easy to mute and move on, but I've taken to not muting other regular chatters just to avoid the confusion it may cause.
