 * captcha-options/string-length is set to “7”. In my servers error-log I am getting
   these:

 * Hello, this is really a pain. I uninstalled and reinstalled the plugin, but this
   is happening still.

 * I believe spammers call plugins/sabre/sabre_captcha.php?sabre_id=xxx directly.
   The error can be provoked by calling the plugin with a too short sabre_id. Can
   this be made saver (using referer, checking that the id is correct)?
