Most of the comment spam I get is from people trying to get referrals. If I turned off the URL autolinking, they would get no click-through traffic.
If I go with the two tier system I discussed earlier, the XHTML comments would still allow comments with active links; however, I could limit such comments to registrants, or make the user jump through a hoop before posting. That might be sufficient to deter the spammer.
Speaking of hoops, what about one of those computer-unreadable passwords, hidden in a graphic? They raise accessibility questions, but there will always be the plain text comment option to get around that.
