yes but they still help.
spammers can get around anything.
there may be newer better methods, but the type-in-the-letter hacks i know of are somewhat labour- and resource-intensive on the spammers, so i think it might be worth a shot.
i was getting several comment-spams per week on my blogspot blogs, but since enabling the 'type in the letters' thing it's dropped to zero. - altho i only made that change a week or two ago, so the sample size is pretty small.

how about adding one of those "type in the letters you see here" jobbies ?
that must be getting to be a fairly standard package by now..

Hi, recently I've been fixing vandalized Swiki pages almost every day - looks like somebody has implemented some auto-vandalizer script or so. Could the nice folks who run the Swiki (hi Mark!) maybe add some code which checks whether the e-mail alert addresses contains HTML tags and reject (or silently ignore) submissions in that case? That would at leas stop this one vandal.
Cheers, Hans-Martin

The method used to defeat that technique has been to have the bot pass the type-in-the-letter image through to a pron site. Users at the pron site type in the keyword in order to see the next image. Then the bot takes the results back to complete the challenge at the first site.
Insidiously clever, co-opting humans to do the jobs which are too difficult for the computer!

yes! ingenious!
that's the method i know of as well.
i think it's still fairly labour-intensive for the spammers tho and they tend to use it on bigger fish such as getting yahoo or hotmail accounts.
it seems like the image could be dickied to discourage that.
i chatted with some folks at yahoo once about like putting the yahoo logo in the image, but they were reluctant to do that because then the Y! logo would be seem to be associated w/ pr0n sites.
anyhow.
if it's easy to implement it might still reduce wiki spam a bit.

Well that is one method I have seen a program that is accurate to about 90% of the time. Even when they come out and make it more difficult they adjust the program parameters a bit and they get it right. I also know of the sites using people but it is in efficient since spammers send on the order of millions of emails every night.
Bttom line it is a losing battle unless the email system redesigned.
