Once in a while you may need to block certain third parties from accessing your Internet sites. There are a number of automatic bots which crawl the Internet, for instance, and create fake visits and traffic. There are spammers who leave links to questionable Internet sites as comments to website articles. Such things could greatly undermine your hard work, because nobody likes to visit an Internet site with many hundreds of fake comments, not to mention that the increased traffic from both spammers and bots can generate high load on the server on which your site is hosted, which may result in the site not functioning properly. Among the most effective solutions in this case is to block the IP addresses that produce the fake traffic, as a way to be sure that the visits to your Internet site are legitimate.
