Whilst certain blocks are currently in place it's evident from the first fews days of activity on the forum that spambots are getting through. These can be an extreme nuisance if left unchecked. Suggestions so far to improve forum security have been:

-Require e-mail verification for all new forum accounts
-Use a harder to crack distortion text picture
-Human checking of all new account requests
-"I'm a spambot" checkbox to be unticked when registering
-Non-standard question when registering, such as "Spell ADOM backwards"
-Filtering of certain keywords used by spambots (xxx, porn, goatse, etc)
-Filtering of messages containing more than 5 links

(the last two could be disabled for members who already have say over 20 messages, and who want to post lots of links and talk about goatse as part of regular ADOM discussion)
