Well....if you know how to toy with trojans...IP's can be devastating.
If you know how to toy with trojans, you'd find getting someone's IP a breeze anyway. Every site you visit leaves a footprint which makes you easily trackable. And I've been to public message boards who post the IP's of their members because they realise that to publish or not is moot.
Anyway, people on dial-up use a different IP address every time they log-in and people on broadband connections should learn to protect themselves with firewall software of some sort (as a minimum) because IP's published or not, they're easy to get hold of anyway.
Your IP doesn't actually reveal anything of your personal details so if you protect yourself, you shouldn't have any troubles.
You being an admin does not in any way give you the right to abuse your power by looking up logs on the webserver and publishing IP addresses at will.
Who needs weblogs? I'm looking at Neil's right now and I just ran a script. All it tells me is his address on a server. I can only do damage if he hasn't protected himself and as I said, regardless of whether they're published, it's easy to get hold of them.
Last I checked, it wasn't illegal to obtain someone's IP address by port scanning their POP, IMAP4, FTP etc. ports. It's akin to someone looking in your windows whilst you're at home out on the street. Sure it's annoying and suspicious but they're doing nothing illegal. If it were illegal to do port scans to obtain IP's, then it'll be illegal for ANYONE to create weblogs of peoples'IP's. Whether Cricketweb does it or someone personally does it doesn't matter; it's not illegal.
Having said all that, if people insist that we don't publish member's IP's then we can just not do it. Fine with me.
