Every website has problems with users . Here is a cool way to ban users who prove to be annoying.
Open your .htaccess file (should be above your public_html folder and you may need to show hidden files), then add the following:
order allow,deny deny from [IP here] allow from all
If you want to add more than one IP, just add an extra “deny from [ip here]” line. On the other hand, if you want to just let one person onto a website just use the following:
order allow,deny allow from [IP here] deny from all
Allowing just a few IP’s to certain areas is useful when protecting administrator sections or user areas.
