Looking for a plugin to show user country

[dragon_1973]

Hi all... I have an older forum with nearly 10,000 users. The last few months we have gotten on some list somewhere that says we are easy to spam or something. In the past few weeks I have had to implemented that new users must be moderated, and added the plugins so that my moderators can moderate users, and added the hack to auto-approve US & CDN users based on IP.

All if great... but what I am finding is those damn spammers have pre-created hundreds (if not thousands) of accounts. We are stopping the new ones from getting created, however the older dormant accounts suddenly start posting spam.

I'm looking for two things.

First, I would like the country of users shown in user lists... not a user-selected country, but rather their registration country, and/or country of their last post based on their IP.

Second, is there a way to kill all users that registered from a certain country? I'm sure Russia is a great country to visit... but I do NOT have any users from there... so any registration from there is almost guaranteed to be a spammer. I want them gone to better reflect my registered users.

Thanks.
