Use the [http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CEEQFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FDNSBL&ei=TS87T7OqE8js2gXdydWlCg&usg=AFQjCNHMIKjC7a5HGB7FYm7RHMsL1x4IXA DNS Blocklists], URI DNS Blocklists and/or [http://en.wikipedia.org/wiki/Akismet Askimet] to keep spammers off of your site. You can tweak the settings to see what works best for your site. Note that you will have to get your own individualized Askimet key in order to activate Askimet.

You can also manually block IPs and IP ranges in the [DolphinAdminIpBlacklist IP Blacklist] section of your Administration Pages.

''NOTE:'' be very careful with enabling '''zomgbl.spameatingmonkey.net.''' - because it will block anyone!



== Example: how to allow only several countries and block all other countries ==


The purpose - we need to allow users from Canada and USA countries and don't allow to join or login users from all other countries.


Add Canada, USA to the while list:

{{{
Chain: whitelist
Domain Zone: ca.countries.nerd.dk.
Return Value: 127.0.0.2
Url: http://countries.nerd.dk/
Recheck URL: [leave empty]	 	 
Comment: Allow CA
}}}


{{{
Chain: whitelist
Domain Zone: us.countries.nerd.dk.
Return Value: 127.0.0.2
Url: http://countries.nerd.dk/
Recheck URL: [leave empty] 	 
Comment: Allow US
}}}


Then enable the following DNSBL:
{{{
zomgbl.spameatingmonkey.net.
}}}
It will block all other countries except the ones you've whitelisted - US and CA.


Now everything is setup but the system is not enabled (by default), to enable it turn on the following setting:
Admin Panel -> Settings -> Advanced Settings > Security > Enable DNS Block Lists


Also this system doesn't block admin, so even if you block yourself - you will still be able to login to your site as admin via admin login page. Only exception is when you enable "total block" setting - so users are blocked before they can login - in this case everyone is affected, but this option is turned off by default, so by default users are blocked during login and join only.
