Blocking comment spam, and other fun stuff

Very long time readers of this site (and you two know who you are) will remember it used to live at another domain, on Userland’s free servers. When I switched over, even though all the content migrated, the Google index didn’t pick things up right away so I left everything in place, put a note at the top of each page with the new site address, and forgot about it.

Until this morning, when I woke up and found two pieces of comment spam on the site. I promptly deleted them and blocked the member who left the comments, but now I’m wondering if it’s time to take more drastic action on that site.

Manila gurus: is it possible to do page-level redirects on a Manila site such that someone coming to ends up at instead?

Or should I just blow the content away? I hate that it’s attracting comment spam.
