A good way to block unwanted visitors to your site is by blocking specific user-agents. By blocking their User Agents, you will stop any traffic that contains the specified name in the user agent field.
A “user agent” is a software agent that is acting on behalf of a user. The format of the user-agent string in HTTP is a list of product tokens (keywords) with optional comments. For example, if a user’s product were called “WikiBrowser”, their user agent string might be “WikiBrowser/0.1 Gecko/1.0. The most important product component is listed first.
