Are you hurting other people’s websites?
Well, are you? To find out, answer the following questions:
Am I running a WordPress site?
Have I done anything to protect wp-login.php?
Have I done anything to protect xmlrpc.php?
If you answered yes to number 1, and no to either of 2 or 3, then the answer is yes, you are hurting your website, and on shared hosting every other website on the same server.
