As far as I can tell, it boils down to this choice:
- either you make it
hard for spammers to reach the form
- or you make it hard for their spam
to be passed on to you
Something like captcha or "duck, duck goose"
accmomodates
the second option. A script that randomly generated some
three-digit number
and displayed it in plain text would probably do close to as
well as a full
captcha, without the cognitive and accessibility load of
captcha.
Alternatively,
you could go with the first option by randomly changing the
location of the
feedback form itself. All other links on the site would
have to auto-change
to match. Or you could manually change the location every
few months, if
it takes that long for your particular spammers to catch on.
Believe it
or not, I have also had success with emailing the repeat
spammers and requesting
that they stop.
