I have a good old, insecure guestbook on one of my websites. It was flooded
with spammers and other junk, so I added a very simple captcha. It basically
says "echo the domain name of this site (four letters)". In the past 4.5
years, not a single spam message has bypassed this homemade check but of
course several legitimate posts.
In the mean time, I have seen other sites using standardized, randomized
captcha solutions get "compromised". Whether those were cracked by bots or
if there are humans behind the keyboard solving the checks, I'm not sure but
it seems to me the more sites that use the same security methods, the higher
is the motivation to circumvent them. My and Philip's sites probably are so
insignificant (sorry, not meant as an insult) that no bots nor human slaves
bother to try and solve the checks.
Oh and back to the original topic: if anyone has need for used 3.5" DD
floppy disks, you can send me an email. I have about 150 of them which you
can have small volumes of for P&P costs. But also remember I'm living in
Sweden so it'd be international shipping.
