But I'd love to have anything that gives us persistent kick bans.Who's for a quick-and-dirty kickban for spammers? (Persistent only for the current server session, possibly a match or a given time)? A console command and new votes would exist for that, too.

So, you're talking about having four voting choices now, right? Acept, Reject, Don't care, Accept for 10 minutes? Something like that?
How easy would it be to work in another configuration setting that basically specifies "after you've been kicked SPAM_SETTING times in SPAM_SETTING minutes, you will be banned for SPAM_SETTING minutes"
