Once in a while you might need to block specific third parties from accessing your sites. There are a lot of automatic bots which crawl the Internet, for instance, and generate fake visits and online traffic. There are also spammers that leave links to shady sites as comments to site articles. This kind of things can considerably undermine your projects, simply because nobody likes to visit a website with many hundreds of fake comments, furthermore the increased site traffic from both spammers and bots may generate high load on the server where your Internet site is hosted, which may result in the site not working correctly. Among the most effective solutions in such cases is to block the IPs which generate the fake traffic, as a way to be sure that the visits to your Internet site are real.
