Currently installation defaults to "Disable board: No" with "Account activation: No activation (immediate access)".

If there was an option to have the board disabled at time of installation, this would stop spambots getting their toe-in-the-door before suitable countermeasures have been deployed.

Thanks for your consideration.

P.S. A similar suggestion was taken up by Joomla - http://joomlacode.org/gf/project/joomla/tracker/?action=TrackerItemEdit&tracker_id=8549&tracker_item_id=27263
