Another function is helps is to provide the number of linkages with various sites that are forwarding their crowd towards the website. The more the linkage, the more visitors will come to the website and more load will be put onto the server to handle requests. Sometimes not all servers are capable in taking the huge load of requests.
So, if the admin ever feels that some linkages are unnecessary and they don’t require those linkages to their site, then they can always block those IP addresses so that traffic doesn’t come from those sites and servers don’t get overloaded with requests.
