Positive captchas are still discrimatory. The reasons for not using them are as valid now as they were then. I guess the question is would you rather discriminate against potential or current users or deal with the spam. Long winded way of me saying we should find a better tool than positive captchas or deal with the spam.

Hi all,
It looks like we may need to improve anti-spam for opac-suggestions.pl.
A negative captcha was added with https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=3144, but I'm noticing a distributed spam attack which appears to either be wise to the "negcap" field or is occasionally lucky to accidentally not put any data with that parameter.
Back in the day, we decided not to go with a positive captcha for accessibility reasons. I suppose we do have a positive captcha in the patron self-registration (I think) so maybe we should add one here. Or. think of something else clever.
Ideas?
