Have any of you ever used the user agent black list?

The 2013 User Agent Blacklist blocks hundreds of the worst bots while ensuring open-access for normal traffic, major search engines (Google, Bing, et al), good browsers (Chrome, Firefox, Opera, et al), and everyone else. Compared to blocking threats by IP, blocking by user-agent is more effective as ageneral security strategy. Although it’s trivial to spoof any user agent, many bad requests continue to report user-agent strings that are known to be associated with malicious activity. For example, the notorious “httrack” user agent has been widely blocked since at least 2007, yet it continues to plague sites to this day. Fortunately, it doesn’t matter if it’s the “real” httrack harassing your site or something pretending to be httrack — you don’t want anything to do it. Implementing a user-agent blacklist is a free and simple way to filter out a large percentage of bad traffic while freeing up valuable server resources for legitimate visitors.
To implement the UA Blacklist, simply paste this into your site’s root .htaccess file (or even better, the Apache configuration file). Upload, test, and stay current with updates and news.
