I've been able to disable my comments using .Text - but only on a per-post basis. Look at the "advanced settings" area for the post and you can uncheck "allow comments". I suppose you could see what that sets in the database and do it for all posts if you wanted.
Anyway, that has worked for me in the past. Maybe check the IP(s) that the spam has been coming from and ban them?
Ryan: unfortunately (or maybe "fortunately"?) the blog is not hosted on my own machine but on weblogs.asp.net, so I don't have access to the database or anything like that. I also don't have the time to go through each individual post in my blog and disable comments for that. The comments are 1 per post right now and counting.
Thanks though :)
Same here... guess we have to start deleting comments?
I've got em too.. if they only had a purpose other than messing up for other people. god darn bastards!
