Related to my comment spam problems (and the drastic solution I "implemented" of simply disabling the script), Toni recently pointed specifically to scode. I looked at something like this (and it led me to consider something similar but with a random text string instead of an image, and in a random hidden text field included in the form), the problem with an image-based solution is that it increases load on the server (every static page calls a script) and I don't want to do that until I switch servers (any day now! :)) since this server is edge already.

Then again I haven't looked for other solutions since late August. I need to get this done eventually -- at this point I am probably just being lazy. Or "spring feverish". :)
