Comment (by cypherpunks3):

 Using [https://trac.edgewall.org/browser/plugins/1.2/spam-
 filter/tracspamfilter/captcha/admin.py this plugin], right?

 If we switch to `ImageCaptcha` instead of the default `ExpressionCaptcha`
 ( https://trac.edgewall.org/wiki/SpamFilter#Captcha notes that the simple
 text-based ExpressionCaptcha is easily bypassed and not recommended, so no
 idea why it's still the default), can we try lifting the restrictions on
 the cypherpunks account?

 What about other tweaks like Bayesian filtering, didn't the spammer have
 one thing in particular they advertised? Could also reduce the amount of
 karma earned from each solved captcha.
