Is there a plug in for Wordpress to have in the admin dashboard where you can see where the IP of a commenter originates from and ban that IP from accessing your site (because they're a spammer). Maybe even have it set up so it redirects traffic from that IP to wherever you want it to go?
Blocking an IP address is not a good idea, because: 1. Most of the IPs are dynamic. May be next time that IP is given to a legitimate user! 2. Most of the spammers use fake IPs so its completely useless to ban an IP. Well as far as your question is concerned. There are many solutions. 1. Best solutions Go to Settings>Disscussion and scroll down unless you see "Comment Blacklist". Here put the IP address(es) (one per line). 2. By Using a Plugin: wp-ban http://wordpress.org/extend/plugins/wp-ban/ This can also be achieved by editing .htaccess file. I can tell you if you are interested.
You can use Akismet plugin for that as well as if you want to block certain ip addresses then do it in your .htaccess file. DON.
Excellent. Thanks for that. IP address can be a bit hit and miss, but there are some locations that simply aren't worth worrying about (in terms of the low quality traffic) but that plug-in also has "referrer url" which will have the most strategic impact in terms of blocking the spammers. Thank you!
