Setting up Maxmind Proxy Detection and GeoIP

I am setting up Maxmind Proxy Detection and GeoIP2 to work with Boonex. I found these old forums for previous Dolphin versions. A lot has changed and I need to know if this is still the best way to set it up. I just want to stop spam joins and I only want the United States to be able to join.

I found this on the web showing how to install GeoIP2:

And I found these links in the Boonex forums:

https://www.boonex.com/forums/topic/Blocking-access-from-proxy-sites-.htm

https://www.boonex.com/forums/topic/How-To-Block-The-Entire-Planet-From-Joining-Your-Site-well-almost.htm

All of those are outdated.  Suggest you install the latest GeoIP2 and the Maxmind  DB Apache module

You can do it the same with build-in Antispam Tools:
