Go into the Cpanel of your site and block the IP address. What kind of software are you using on your site? Is it a forum or a blog? What kind of software are you using - are you using wordpress, joomla, postnuke, phpnuke, phppost, vbulletin, phpbb, mdpro, IPB or phpcow???? A lot of CMS's have a "Block IP" feature in the control panel. A little more information would be nice.
I'm using Wordpress. I'm about to check out the Block IP feature. I haven't seen it yet to be honest.
If your hosting company is using Cpanel, log in and look for "IP Deny Manager". Sometimes its in the bottom left hand corner of the main Cpanel main page. Enter the IP address you want to block and save your changes. To unblock the IP, that function is in the "IP deny manager" as well. Once you add an IP address to the blocked list, it will show up in a drop down menu. So just select the IP, and click remove and the IP address will be unblocked. There is also a thread here about blocking IPs - http://forums.digitalpoint.com/showthread.php?t=47469 And check out this spam blocker program for wordpress - http://unknowngenius.com/blog/wordpress/spam-karma/
Aren't IP addresses of visitors considered privileged information for the website owner? Such as not to be posted on a public forum even if he or she is spamming.
Isnt highjacking a thread when someone ask an off the wall question and try to derail the thread from its original topic?
Block this entire CIDR : 193.53.87.0/24. Easier if you are on your own dedicated server and use a S/W Firewall.
Go to your .htaccess file at place this in there: ## USER IP BANNING <Files *> order allow,deny allow from all deny from 193.53.87.81 </Files> Code (markup): The IP will now be blocked from accessing your site...
