There's not an easy way in any version, but if you search the forums you can find out how to do it. The best thing would be to upgrade to 0.9.1 , it does the best job of handling spam. If your webhost doesn't support it (I don't know what the problem would be) then you could always back up your database and move elsewhere. I think your time would be better spent trying to get help doing the upgrade than trying to hack core files of an old version to remove a built-in feature.
