StopCountrySpam might be useful: http://xenforo.com/community/resources/stopcountryspam-spam-combat.1016/
It does a look up for the country code at the time of registration (it uses the IP to look up the country code from external database .. which can be defined by you, and looks at the JSON response)
An on the fly look up makes sure you are not using an old IP address association that is no longer associated to the same location (as long as you point the plugin to an up-to-date external DB)
I've also provided links to lots of external sites that will alow you to use their JSON response for country look ups, see here
Supports white list / black list options
Supported by me, let me know if you need it to do anything else
Useful for local community forums (where the conversation is expected to be local only), but this plug-in may not be for everyone.
- This is good for stopping manual spammers from know countries (not all use proxies), but many people who use bots will use proxies, so keep that in mind
