Improve Spam Fighting
A few spambots are apparently getting through the captchas.
So far, the few that are getting through we could easily get rid of by simply banning the word "sexchat"
This could be done by using this module:
I do not want to go for a more advanced captcha. The current one is only displayed to anonymous users, and I tried to pick ones that do not need to be translated to be figured out.
In hindsight, maybe I should get rid of the css letter based one. Not everyone uses this alphabet.
