Good morning

I just received this link via the Blind Programming list, and thought
it would be worth a read and a discussion here as well, as many people
must get questions regarding CAPTCHAs and possible spam detection
mechanisms out there.

The honey pot mentioned, that filters out spammers by having an
additional hidden field, whose input indicates bot activity, since
bots interact with the raw html bugs me, after all screen readers do
that too.
Admittedly the label could indicate that this is a type of filter and
no data is required, but that could do away with the usefulness of
that field, since relatively simple language detection might help the
spam bots.
Either way, this is a very interesting discussion of the problem and
the solutions, and accessibility definitely gets its fair share of
attention.
Cheers
