One that is less cumbersome than the "type in the word in the weird
image" approach is to set a cookie-like hidden parameter from the server
when it generates the form (I'm assuming php or perl behind a dynamic
server). In the cookie you can put the timestamp and encode the thing
using a simple cipher. When you get the cookie back, you check whether
the timestamp is within a reasonable range. The spambot would have to
refetch the original form, insert his crap and resubmit it, since it's
not able to generate the hidden parameter on its own. Most (all?) won't
do that.
Well, IMHO this is no better than my solution using JS
What do you do if someone has cookies disabled?
I for my part often reject cookies 'just because' when I dont feel
they're really needed...
So I dont know which part of all surfers is bigger, those with lynx or
those with js disabled
Actually in the last 7 day there wasn't a SINGLE lynx hitting ALL of my
hosted domains...
But of course this is always a matter of opinion and it can vary a lot
depending on the website.
But IMHO if a user using lynx cant add an entry to a guestbook this is
no big loss for me...
Just my 2c
