I noticed there are lots of spam-posts in the issues on redmine.kannel.org Examples: https://redmine.kannel.org/issues/322#note-10 https://redmine.kannel.org/issues/95#note-13
Would you consider adding a captcha for the self-registration / anonymous users comments posting? Here is a captcha plugin for redmine: https://github.com/egroeper/redmine_recaptcha
