Given that there are algorithms that can solve our
captcha presumably they

to use those algorithims. I would guess that text on an image without any
blurring or manipulation would be just as hard for those sorts of people to
break. (Obviously that's a rather large guess). As a compromise maybe we
should have straight text in image captchas.
A simple thing that could be done is to introduce localized captchas on
non-Latin wikis (just remember that not everyone has the appropriate
keyboard). This would mean that new captcha-cracking algorithms would
need to be developed for each script, and if the wikis are small,
spammers would not bother.
